| 850 maintnence costs and such Hey Ive been wantin an 850 for a while now but as far as BMW V12s go they are sick as shit. Only thing is how hard to change the plugs and do typical maintnence? I know the intake manifold gaskets on any BMW V8 or V12 need changed every 40k or so, but is there anything that really gets owners on an 850? |
