I have a 2000 Audi S4 and am about to roll over 100k now. My car seems to run strong still, but now I am thinking about putting some mods on it. Is it really worth it with all these miles, or should I hold onto it and get a newer S4 with less miles in another year and mod that?

 

have you replaced your turbos yet? Cuz if you havent then you should do that before modding and to solve both of those problems at once you can just drop some KO4's in there.

 

doing anything that would change the boost would make me a little uneasy with high mileage

 

ehhh with 100k, i wouldnt. id save up ur money for either another car down the road or for repairs
