550 is a wonderful car but it is no M5 in terms of power and speed. Try going up against one from a light at WOT. It is embarassing if you are in the 550. 550 is fast. It is not blazing, balls to the wall, head snapped back into the headrest fast.

I really like my 550 but I wish I could spend the extra dough on a M5 or swap with a M5 leasee who had gotten a good deal on one.

Don't do it. Stick with MB.

:lol:

M5 is the way to go!!!! very nice drive but it drinks alot.....

Bwahaha!

The M5 is a tremendous car, but given the car you're coming from and what you're likely to have to invest in the upgrade to an M5 you ought to consider the C63. It's exponentially better than the standard C-Class. The E63 is also well worth a look. It rarely gets the credit it deserves on here, but it's a match for the M5 in most respects - it loses out in some areas, it's arguably better in others.

C63 is a real rocket but would be too small for me.

E63 is faster than the M5 in a straight line but not as good a handler. The low-end power and torque are better in the C63 and E63 than in M5.

Both are worth a look though. I prize handling so it would be M5 for me if money was no object. But if I lived in a place without much in the way of twisties (like South Florida), I might very well get the E63.

:lol:

C, you crack me up.

Dumping the M5 for the MB are we?

Dude your C will get smoked by an M5. If u talking CLS63 or M5 diff story............
