Hi comrades, I am thinking of buying a 117k s3 8P 2009 stage 2 uprated intercooler, rts clutch, coil overs, Uprated induction kit, 3 inch power flex exhaust, well maintained (or so they say) and with full service history. Cam belt and water pump done at 92k. my question to you is your opinion on the matter with things such as: 1. Would engine make it to between 150-200k miles and what would help to increase durability. 2. are these cars as reliable as folk say, (not comparing it to Honda engines) if so why, if not how come. 3. I would get a lower mileage stock one but don’t fancy forking out 1k to get clutch when i stage 1 but would it be better off doing this rather than buy car already modded. 4. What to look out for if I go see the car. thanks
