Well, the issue with the E30 is that its safety features are going to be a bit outdated. Airbags, explosive seat belt tensioners, abs, dsc/asc, and probably more technology into the design of crush zones and the like.
Just saying...easy to work on and reliable, but not as good in an accident. Sorry...something serious to think about. e46 is pretty good in that regard...although I'm sure newer models have more airbags hiding around.
