I would recommend an e60 M5. I purchased a new 550i msport in 2006 and drove it for 2 years, then got the bug and purchased a used 2006 M5 CPO (SMG) which I have had coming on 3 years. Absolutely LOVE the car. I leased it an it's over in October. I don't plan on keeping it since I will have been 5 years with the e60 platform. I consider my self a "car collector" but my wife will only let me collect 2 at a time....lol....so the M must go.

I am about 10 days away from delivery of my 2007 C2S cab (can't wait!!!!) and will replace the M5 with a used Mercedes sedan.

I am happy to answer any specific questions you have about the 550 vs the M5. Also check out e60 forums: http://forums.5series.net/ I am there with the same user name.

GL with your decision!
