Size wise, I would like the M.

Price wise, I'll just stay with my 2004 G35 for awhile.

The only former vehicle I've driven for less than about 6 years was the 67 Impala I drove for a couple years in high school before the engine fell out.

I can understand, for those that can afford it, the allure of leasing a car and getting a new one every 2-3 years. If I was that type, I could be getting the 07 when it came out, then the 2010 when it is refreshed, etc. Or deciding to get the 6MT since it isn't like you are stuck with a manual for 6 years if you decide you don't like it.
