Bought a used car 2017 330d M Sport off this (Garage), and after a few weeks the car drivetrain warning light came on, and the car went into limp mode. So I took it to the BMW specialist at Lloyd South Lakes BMW, where they said that someone had put petrol into the diesel tank. And that they had tried to rectify it themselves and very badly. Once they realised it was going to be an expensive repair, they bodged it back together. The BMW garage had to refit all the fuel hoses, and replace a fuel pump, 6 fuel injectors, and a fuel filter because they were all contaminated with petrol which caused the car to cut out while the car was been tested for tge drivetrain problem. In the end it has cost me £7887 to get the car as it should of been when I initially bought it. I rang the owner where I was told it was OK and passed everything. That's not what the BMW specialists said. I rang Sheffield Street Motors 5 times and each time he had an excuse to hang up but said he'd ring back, which he never did. In the end he never even answered my calls. What he did say on my first call was to sell the car on Webuyanycar.com and he'd make up the difference!!!!, I'm writing this to warn anyone who is even thinking of buying a car from Sheffield Street Motors. Be warned, he's not to be trusted and you'll probably be buying a car that's just come straight from an auction and put straight onto the forecourt with no checks or anything. Wish I'd taken my own advice, but a very expensive lesson learned. But please STAY AWAY from this garage!!!!

Refused to give a receipt for the car I purchased and left me with outstanding ULEZ fines to pay on the vehicle.
