M3 vs 850i

I'm looking at either purchasing either a early 90s M3 or 850. Its a hard desicsion because they both have so many great characteristics, and a few down sides. Any comments or sugestions on the idea?

Both are nice cars but for different reasons. Will it be a daily driver or a weekend cruiser?
IMO: Daily-M3, Weekend-850
The M3 won't cost as much to feed or maintain, but the 850's are unique.
