Okay, so i already posted this thread in the a4/s4 forum, but wasn't sure if this was the appropriate place to post this thread, sorry, very new to the site. Hi, i am new to this forum and am very close to purchasing a 98' or 99' a4 1.8 t quattro. Anyway i want to get one with around 50 or 60k mi, but i have read some reviews about there being a lot of mechanical maintanence issues with the car at around 80k-100k mi. Is this true, and if it is, what are the most common problems and their expenses? (ie: should i buy this car?) thanks for the help in advance.
