Alright lads, first time on this forum so if this is in the wrong place sorry. I'll be buying a 2002-2004 Audi A4 1.9 TDI soon and im wondering is there anything I should be cautious about when going to look at one for sale eg Common rust locations, bad points etc etc. Also im looking for one with the S-Line bodykit on it which i've seen is quiet expensive, is it cheaper to buy one with the S-Line kit fitted or buy the S-Line kit seperate and fit after the car is bought.
