Im looking at an 08 320d and the dealer is saying it had the timing chains done in Duffys but the service history has gone missing. I know i should probably walk away but the car is priced below market and ive bought off the dealer before with no probs.

So the question is can i call BMW to ask when this work was done and at what mileage it was done at. Ive have the Reg No. and the VIN No.

Any advice appreciated.
Cheers
