Four months and five days later I got my car back, it is almost perfect - by that I mean as it should have been when I bought it! At a guess I put about 7-8k miles on their cars
Minor niggle with the phone which will only connect at 2G, they have referred this to the factory for support which may take a while. They are going to extend the warranty to cover the time they had the car also.
It maybe a few years older than the 15 plate loan cars I have had, but it felt good getting back into my own car with all the options I wanted, and the V8 is so much better than the V6 TDI
