Hardtop convertible is best of both worlds. Was also considering C63 AMG and 911 SCab. The M3 performs better than 911 for $30k less, and out laughably out handles the AMG -- I also owned a C55 AMG previously and a Z06 Vette. M3 has the best balance of comfort, power, and handling of any car I've owned. I highly recommend the Tech Package for now other reason the the M-mode -- this allows you to change suspension, throttle response, and steering response with push of a button and transforms the car instantaneously (almost like a different car). The V8 sounds incredible and can't wait til spring so I can hear it with hardtop down. Must haves are Tech pkg, and upgrade wheels.
