Guy's feel free to correct me if i'm wrong
Out of the issues most people have had with their cars, the only one that really concerns me, and i'd consider bad luck if i land myself with car that develops it, is the Gearbox.
Things like the dampers dont' bother me, as soon as the stock Drc plays up, whether that be the day i buy it or after a year or so, i'll just replace with coilovers, the £1500-2000 expense has been built in to the budget for 1st year repairs
The alternator isn't really a problem, again it's an expense you don't want but it could go at any time, could buy a minter for 20k and the alternator could still pack up the day after you buy it.
Brakes and tyres are a bargaining tool for the sale, worn out and you want to be saving £1500 or so, new and it makes the car more saleable.
Now i don't want to come across as knowing it all, as i'm sure i know less than most on here when it comes to speifics about the RS6, but the points i make above could be true of anycar despite a 10k sale price or a 20k sale price.
Some other things i'm keen to check up on are the past history, service history, correct maintanence, cambelt change or changes for those approaching 8 years.
I'm keen to hear peoples thoughts on the prices though, Book price for 2003 80k car is 12k on a forecourt
Any Advise people can give me would be much appreciated.
