I bet they cost a pretty penny to maintain. attach an M badge to anything and the price goes up. I would think if you maintained it yourself it might not be to bad, just don't hit anything. I have considered picking one up for a daily driver and fun dayz at the track, but for the same concerns have backed off and now I would consider a E36 325. They are competive in ITS, prolly can run with the E30M3 without the inflated parts costs. They also have improved reliability and better suspension.
Something to think about!
