2006 BMW M3 Convertible 2dr Convertible (3.2L 6cyl 6M)
Outstanding Performance and Handling
 I considered the Cadillac CTS-V, BMW 335i, Audi S4, and Infiniti G35 before deciding on the 2006 M3. This was the most expensive of the lot, but the overall quality and driving experience gave it the edge. The back seats are large enough for adult passengers, the instrument cluster is user friendly, (no iDrive) and there is enough storage space to make it a functional car for daily driving.  The suspension and handling are better than any car I have ever driven, including my dearly loved '99 corvette. The manual transmission is excellent. I highly recomend this car.
