Hello all, ive been registered for about a year now, since ive had my a4 2.4. Ive read through the stickies and days spent reading posts. Ive got £2k and i want a a3 t sport. Love an s3 but it aint happening on this money. Im still none the wiser on what years give what engines.there seems to be alot of overlapping. Ayr's, abc's, agu...tf's.... Arrrgh! Should i know? Do i need to know? 180hp versions and 150hp? How do i tell when i goto view some. My money would seem likely to fetch me a 51 or 52 plate. My long term plan is to get an a3 upto s3 territory, spread out over a couple of year mind. Anything to look out for? Should i worry about mileage if the service history is there? Id appreciate any advice cheers.
