I have wanted a convertible sports car for some time and finally stepped out and bought the M3. Titanium Silver with a Black Top. It is a great machine that is tight, well built and fast. It turns head everywhere I go. I am just about to complete break in period so I can begin to respond to the frequent challenges I get on the road. You can't rev over 5500rpm or exceed 105mph on break-in.
I added the 19inch alloy wheels (sweet). This thing corners at high speeds with a breeze. You feel and control the road.
Figure out way to use smaller components like CD player and Nav system so you can have both
