Hi Just joined because this looks like the best place to get a spot of info about an A4 avant!I'm looking at buying one as my other car has just been writen off! Needs to be Diesel. I've got about 5-6K to spend and after a quick look on the old autotrader i think i'll be able to get something.Anythoughts on difference between S-line and sports?First question anything nasties i should be keeping an eye out for? And whats to high mileage? seen some which are in budget and are newer but have around 140K on, I do around 18k a year.Whats the better to have an older B6 or a newer B7 but with more millage?I'll thank you all in advance for any help and tips!
