It's where I got my Legnum VR4 from. The car has a number of minor faults (brakes shot to pieces, gearbox ropey, though the later was fixed with a tranny flush), other than that it's ok. Certainly not bad for £5500. They also said they'd change the tyres for the MOT and I'm far from certain that they did.
I got the same impression when I called them, they really didn't seem that fussed and I did a 400 mile round trip to get the car. The warranty thing sounds cobblers though. The warranty I have covers me for 6 months and up to £200, stuff you only find out about after reading the small print. They recommend you get the cam belt changed as well so add another £300 to the price.
Other than that, they have some very nice motors parked on the forecourt, there's another big dealer next to a pub on the roundabout down the road. If you're thinking of going then pay them both a visit perhaps?.
I'll score them 7/10 but only because it was the most fun haggling over a price that I've ever had.
