Totally different experience from the Z..rides nice, shifts smooth and the inline six is pretty much bulletproof. Lots of low end torque and cruises great. There have been some problems with the cooling system on these like someone else said - plastic water pump impellor, plastic thermostat housing, etc...but all have aftermarket components that are aluminum that are durable. Also have heard the rear shock mounts can crack but mine hasn't had any problems. Another good site is [ www.bimmerfest.com. ] Email me for any more specific questions.
