Beware the used car buying scam that makes your vehicle appear faulty...
A scam targeting private car sellers appears to be making a comeback - and drivers planning to advertise their motors for sale need to be vigilant for the dirty tactic deployed by fraudsters.
It sees con artists arriving to test drive a car listed for sale by owners, only for them to tamper with the engine bay to make it appear like there's a major issue.
They do so by pouring oil into the coolant system. When the engine then billows smoke, the unlawful potential buyers will claim there's an issue.
But instead of walking away from an apparent faulty vehicle, they offer to take it off the seller's hands for around a third of the asking price.
The criminals usually work in pairs, with one distracting the owner while the other decants engine oil into the coolant system.
The Daily Mail has reported on numerous instances of the 'dirty oil trick' being raised to police in the last few years, as criminals attempt to con unsuspecting car owners out of thousands of pounds.
One instance saw two brazen scammers attempt to con an unsuspecting BMW owner from Norfolk out of £6,000 by pouring engine oil under the bonnet before asking him to sell it on the cheap.
How the dirty oil trick scam usually works
Each time a scammer attempts this trick there are of course nuances - but it typically follow a similar pattern.
The scammers will express interest in a car that a private seller has advertised and schedule to visit to view and test drive it.
Usually the scammers will come in pairs or threes, sometimes even with kids in tow.
While inspecting the car and the engine, one of the group will distract the owner - asking to see the paperwork, or the spare wheel etc - while another one of the group contaminates the coolant with oil.
A few quick squirts of oil into the coolant system (and often the exhaust pipe too) will cause the car to smoke when it starts or shortly after embarking on a test drive.
When smoke starts billowing, the criminals will then ask to check the engine again and claim it is about to fail.
This will trigger a derisory offer to buy the car for scrap.
This is Money has heard of a number of cases of this tactic returning.
The Daily Mail has previously reported a spate of instances over the last few years.
In 2022, BMW owner Bikramjit Kooner caught two shameless scammers on CCTV attempting to con him into selling his 10-year-old 520D M Sport for a faction of the price he was asking on eBay marketplace.
While one man distracted Kooner, the other put engine oil into the coolant and put more oil on the side of the engine to make it smoke.
After the car started smoking on the test drive, they told him it was 'fucked' and offered to buy the car 'as scrap for £2,000'.
Similar experiences happened to husband and wife Martin and Natasha Hill from Kent in 2019, and John Woodcock from Manchester in 2016.
Mr and Mrs Hills were trying to sell their Audi A4 through classified advertisement website Gumtree when the same 'dirty oil trick' was pulled and the two men offered £1,000 to £2,000 less than the asking price - on certain 'conditions'.
This too was caught on CCTV, as was John Woodcock's experience with three Bulgarian men who came to view his BMW E39 in 2016.
He'd posted it for sale on Gumtree for £1,750, but the men only offered him £500 after distracting him and emptying a bottle of oil under the bonnet and claiming 'damage'.
In all cases the cars luckily didn't suffer lasting and expensive damage because the owners were wise to the scheme before attempting to drive them, so the systems could be flushed.
How to make sure you don't fall foul of the 'dirty oil trick' scam when selling your car
Firstly make sure you have someone with you, a friend or family member, when anyone comes over to view your vehicle. This will make sure there's always someone with eyes on the front of the car, watching for suspicious behaviour.
Take pictures of your car's engine bay and coolant bottle, which clearly shows the coolant colour and the oil colour. The time stamped photos will be proof to compare back to.
Clearly demonstrated the oil dipstick, the cap and the coolant colour and cap before you start the engine and go for a test drive - it will show any potential scammers you're aware of the trick.
Make sure you and your friend or family member do not leave the car viewer unattended at any point.
If you discover anything's been tampered with then don't drive the car until you can get a mechanic out to fix it - this way you can save yourself money on potentially costly repairs.

These BMW Models Will Be Most Affected By Imminent Price Hike
If you want a new BMW, now is a good time to buy one. Not All BMWs Will Be Affected, Though If you want a 2026 BMW, the time to buy one is now. On July 1, 2025, the German automaker will be increasing prices of its 2026 models, according to Cars Direct. Depending on the model, you could be paying up to $2,500 more from July, with an increase of up to 3% on selected models. Although it's easy to assume these price hikes are a result of tariffs imposed by the Trump administration, the report suggests this isn't the case. Instead, BMW suggests this is a more usual increase that takes inflation into account. So, which models are impacted by the July price increase? 0:03 / 0:09 Audi A5 replaces A4: So, what's changed? Watch More High-Performance SUVs Receive Largest Price Hikes Source: BMW BMW's X5 M and X6 M Competitions will be $2,500 more expensive from July, which represents the biggest increase in dollars – but not necessarily the biggest increase percentage-wise. While the MSRP for the hottest X5 is $127,200 now, it will rise to $129,700. The X6 M is currently listed for $132,100, so will go for $134,600 once the increase takes effect. Fortunately, more modest increases await BMWs at the more affordable end of the scale. The cheapest BMW 4 Series will be $1,100 pricier; it currently starts at $51,500. The same $1,100 increase will apply to the base BMW Z4. The six-cylinder Z4 M40i, which will remain in production for longer than expected, may receive a slightly higher price bump. Cheapest BMW M3 Still Under $80k Source: BMW A few days ago, the pricing of the 2026 BMW M3 was leaked, and it's going to be $2,380 more expensive than before, now reaching $78,400. This price excludes the destination charge. The quickest M3 Competition with xDrive all-wheel drive will cost $87,700 before destination charges. Despite this increase, the base M3 is still a lot cheaper than the 2025 Mercedes-AMG C63 S E Performance, which starts at $86,050.

All EVs are excluded, along with the M2 and any 2025 models. Furthermore, the cheapest new BMW currently costs $39,600, and that's for the 228 Gran Coupe. Even a relatively small increase would mean that there are no more new BMWs for below $40k. However, the 2026 Gran Coupe will also be excluded from the price jump. On the whole, it appears BMW has done a decent job of mitigating the effects of tariffs. We know that BMW, along with fellow German automakers Volkswagen and Mercedes, are in talks with Washington to reach a potential tariff deal. If successful, the deal could lower or offset tariffs for models imported into the United States. About the Author Karl Furlong View Profile

Hydrogen cars are definitely (maybe) still going to happen
Future Tech People are still trying to make hydrogen work for cars. Here's how fuel cells still might make it Skip 2 photos in the image carousel and continue reading They've been a long time coming, but hydrogen-powered cars are definitely still on. Maybe. "Hydrogen is coming after everything else. Solar, wind, batteries; all went through a massive cost decline curve," insists Chris Jackson, founder of hydrogen solutions firm Protium. "The problem with [hydrogen] is everyone wants to jump to the end." Feels like it's been that way... forever actually. How many false dawns and dead ends has hydrogen led us to over the years? Advertisement - Page continues below But speaking at a forum organised by BMW last week, the project managing chief for its hydrogen tech, Dr Jürgen Guldner, observed: "We need to get over those few first 10,000 units where economies of scale make sense, and then the cost curve will come down." So here's a theory: the road to hydrogen cars is via trucks. Guldner points out that 12 per cent of HGV operators planning to introduce hydrogen vehicles within the next five years: doesn't seem like a lot, but that's because businesses are worried about infrastructure. You might like Jackson steps in: "Hydrogen infrastructure is more expensive because a 50kW EV charger services up to 10 cars a day, versus a hydrogen refuelling station doing 400 vehicles a day. 'That's why in Europe [the attitude is] 'let's get the heavy-duty vehicles out first'. Create the demand, create the backbone. Then that creates confidence and certainty to bring in passenger vehicles." Advertisement - Page continues below Feels like we've had this chicken and egg debate a thousand times over, but despite the beleaguered progress of the tech since the 1966 Chevrolet Electrovan, people are still trying to make it work. Hyundai's got the next-gen Nexo coming later this year, and BMW's iX5 pilot was so successful the German carmaker is readying a production fuel-cell electric vehicle (FCEV) by 2028 using Toyota technology. According to Toyota, there are 75,000 fuel-cell vehicles (FCEVs) on the road globally, with the Mirai accounting for around 28,000 of those. The UK's contribution to that sum is 230 Mirais... and roughly 20 hydrogen buses in London. Don't judge, eh? But here's the scale of the problem: here in Blighty there are three publicly accessible car refuelling points, with a further three planned. And four publicly accessible bus refuelling points, with a further... two planned. Thank you for subscribing to our newsletter. Look out for your regular round-up of news, reviews and offers in your inbox. Get all the latest news, reviews and exclusives, direct to your inbox. In total there are 16 hydrogen refuelling stations across the UK, and funded plans to build enough to enable north-to-south travel (roughly 65). Calculations suggest the UK would need around 1,300 to put every driver 30 minutes from one. So the gap is big. Really big. Refuelling hubs can take one of two approaches; one where the hydrogen produced elsewhere arrives by tanker, the other where the hydrogen is produced on-site. Jon Hunt, senior manager of Toyota's Hydrogen Transformation division, says: "What we've learned is while it's very good [to produce on-site], it does need scale to make it economically viable. So it's better to centralise large-scale production and look at the distribution routes." Meanwhile hydrogen is being used in other places, powering sound systems at music festivals and lighting motorway towers – things which should help drive costs down. So going to see Oasis this summer is actually you doing your bit for the planet. "You gotta roll with it! You gotta take your time!" Ahem. Add in fancy innovations like the portable hydrogen cartridges (pictured) that Toyota's been working on, and some cars to actually run on the stuff, and the pipe dream might not be dead after all. Maybe.

Twice Superbike champ Razgatlioglu to ride for Pramac in MotoGP in 2026
June 10 (Reuters) - Twice World Superbike champion Toprak Razgatlioglu will make the switch to MotoGP in 2026 after agreeing to join the Prima Pramac Racing team, Yamaha announced on Tuesday. Razgatlioglu, the first Turkish Superbike world champion who is known for his showmanship and has 63 wins, won his first title with Yamaha in 2021 before making the switch to BMW, winning the title again in 2024. Pramac made the switch from Ducati bikes to Yamaha this season. Razgatlioglu is currently second in the 2025 Superbike championship. "Toprak, the most victorious Yamaha rider of all time in Superbike, has proven to be an exceptional talent, securing the WorldSBK Title twice, which is no mean feat," Paolo Pavesio, the managing director of Yamaha Racing, said in a statement. "His transition to MotoGP is both a 'homecoming' and an exciting new challenge that's been set up with the clear goal of progressive growth over time." Razgatlioglu had previously tested the Yamaha bike in 2023. Pramac currently have Jack Miller and Miguel Oliveira as their riders this season, with Yamaha saying the 2026 lineup will be confirmed in due course. Current WorldSBK leader Nicolo Bulega is also set to join Ducati's MotoGP test team next year ahead of a potential switch in 2027 when MotoGP's new regulations come into effect.
