I have narrowed my choice down to the G35 6MT Sport and the new 330i Perf. Package 6MT. Anybody have a chance to drive both extensively? I have driven both once on a test drive, but unfortunately in city driving only (never exceeded 3rd gear). There is a fairly large price difference, but what about the performance and other factors? With the extra HP, new 6spd trans, and different rear end in BMW, it gets to 60mph in 5.9 sec (probably about the same as the sedan 6MT).
