I think it's something you should try after driving other cars.
I took driving lessons in all kinds of cars and even a truck.
My first car was an e30 316i and I kept it for 8 months untill I saw it was too far gone to restore it. So I went to search out the most durable chassis type combined with a fairly low maintenance engine and The best option for me turned out to be the e34 520i with the M50 engine.
Either way, it's like I tell lots of people when they say "nice car": You should either have a big wallet or be prepared to do lots of research yourself if you want to keep a car like this one.
The driving experience is worth it though, and I wake up thinking "Yay! I can drive my car to work today!"
As far as research is concerned: I'm a newbie here, but I get the idea that this is an awesome forum to get info and even slightly being a part of such a community is heartwarming.
