Hi guys, I'm looking to buy an Audi A4, I imagine the B6 model as my budget is only up to £3.5k. What should I look out for when viewing/buying? Obviously the approximate mileage of the cars I will be looking at is going to be over 80,000 miles so I'm just wondering what I should be looking for with an A4 of that approximate milage, obviously the cambelt/waterpump should have been replaced by then but apart from that I don't know :/ Also I don't know what engine to go for? I could go for the petrol 2.0 FSI, at roughly 80/90k miles, or a diesel version which will probably have over 100k on it, I don't do many miles probably less than 9000miles a year. I just want one which will last me 4/5 years to run around in which will be reliable, I'm not too bothered about how powerful it is, my main concern is to get the most reliable engine! Any advice/comments would be appreciated, thanks.
