Hey enthusiasts, I currently own a 1988 735i, and spend about $2500 a year in maintenance. This year I spent $4000(new trans and new headgasket and other stuff). I'm wondering how similar in maintenace costs the M5(1994) will be. And I also wanted to know how many of you current M5 owners use them as daily drivers. I plan on buying one within the next month or so, and was wondering if they make better weekend cars than daily drivers.
