S3 Nah the best thing to do if you want it is to ring the dealer that did the repair and ask the guys there if they would buy it, then get a quote on the car and you'll see how much extra the running cost are. Against all the comments here if the repair has been done to a high standard the car could be "as used" (not new). It is always risky buying a Cat D, it is unlikely somebody really got a dealer involved as the costs would be high but if they did it should come with some sort of cover should they have missed something. However if you think you'll have no problems selling the car on, just read the comments above - you are in the minority buying a specialist car with that kind of history. Best value in the long term is buy the car with the best history, care for it and get it serviced. The cost of the car is not what you pay for it in the first place but the diffence between what you buy it for what you sell it for and all the costs in between! PS for what it's worth I wouldn't!
