I've always loved the way the e36 cars drive. The M3 e36 is a really nice package. Get a 1996 or later model. The first model year ('95's) had a 3.0l six. Later models had 3.2liter engines. Also check the rear trunk floor for damage. Its very common for the rear suspension to tear/break the trunk floor on e36 and e46's. All in all the e36 is a really nice car to drive. You will enjoy it.
