Purchase advice Audi 80 b4

Hello together! I was looking for an Audi 80 b4 and came across this forum. It would be great if you could give me a few tips. My ideas: * Price approx. € 2,000 (so that I also have some reserves for repairs) * max 150tkm * 90hp machine * D3 In the forum in a different thread was generally discouraged from the 2.0 90hp, without further indication of reasons. Was that just a personal preference or are there problems (consumption, durability, AU)? Weak points, what should be paid special attention when buying? Topic Biosprit: Audi generally writes no problem from 1992 onwards (http://www.audi.de/…/…_for_planned_E10-fuel_suitable.html) Does this mean from model year 1992 onwards? What else would I like to do with the 91er b4? I would be really grateful for your help!
