I’m on my third now, they’re addictive! Agreed, I just came back from an e39 523, good car, but as you say, parts are ridiculous prices... particularly wheels! And I’ve been driving it the last couple of days and just feels far too sedate for my liking.
I think that’s just part of the security system, in my Impreza you have to press the unlock button while it’s in the ignition to start it.
