The M112 and later version 722.6 are indeed as reliable as a wood stove.

That said I've drive M112 and M272 versions of the W211 and while I wouldn't exactly call the M112 powered version 'slow' its noticeably more pokey than the later M272. I think the M272 has something like 50-60 Hp over the M112?

I do agree that the balance shaft issues are potentially a huge problem, if I were in the market for a gas powered W211 I'd be looking for a later M272 that was out of the danger zone for balance shaft problems or had already been fixed. I also think the MY07 facelift features and interior upgrades are a nice touch.

It also seems like most of the later W211's had factory nav, phone and SAT radio options. After living with these creature comforts for a few years I know I'd miss them if I had to give them up!!

The W211 is quickly becoming my favorite MB chassis of all time. Great car.
