I have a 3 year old M6 and haven't had to put a dime into it yet, thanks to BMW's maintenance plan, and I havent' had to any warranty work done at all. I will tell you that I have had WAY more little things wrong with my 3 year old 328xi than my M6. The M6 hasn't had to go in for ANYTHING other than routine maintenance unlike my 328. Maybe when it's older it may be expensive, but what BMW isn't.

People always talk about the gas mileage being so bad, my car's computer says 20mpg at any given time combined city/highway, which is just fine with me. I say go for the M5 and don't look back!
