As promised a short while ago, here is my update on today's testing on a 6MT sedan and coupe.
Since most of the 6MT coupe are sold, the salesman gave most of the testing on their 6MT sedan demo car, a good 25mins drive on a mix of different road types, 6MT Coupe testing is very limited.
The 6MT-S engine is definitely noisier and less smooth, the whole drivetrain shakes a lot. 6MT Coupe exhaust sound improved the acoutics siginicantly, the drivetrain is bit smoother than the 6MT-S, but still not as refined as the Bimmer.
Both the 6MT-S and C give very good turn-in feel on corners, they both corner well, less body roll than my 330ci with sport package. However, the front lift from a standing start and dive from braking is very annoying, I don't mean smoking start and then stomp on the brakes, just from normal easy going stop-and-go traffic, the 6MT-S makes me feel like sea-sick, don't have enough time on the 6MT-C, so can't confirm the degree of annoynace yet. The 330ci has much better anti-squat and anti-dive suspension setup, hence, the car feel easier to speed-up and slow-down, i.e. more connected feel on acceleration and deceleration, no annoying up and down movement. I explained to the salesman who sit on the passenger side, and he also noticed the "bouncing" on the 6MT-S ever since I mentioned it. (BTW, he currently owns a 2000 328ci, and had spend some auto-X track time before)
The 6MT-S suspension is too soft and the unrefined drivetrain makes it hard to steal my heart from the Bimmer camp. The 6MT-C is much closer, however, I'll need to find more time behind the wheels to reconfirm.
The overall driving feel is still a bit less connected than the bimmer. My E46 feel easier to get it going and glide along, while the 6MT-S need to give a bit more initial push.
Many folks on the forum complained about the cheap-looking interior material, but I find they're on par with the 3-Series. I do notice the shortness of the armrest, the wierd shaped oil dipstick, and those misplaced cup holders. Well, they're not perfect, but a very minor compromise.
Since a BMW dealer is willing to give me a great 3 year lease deal on a 2004 330ci, and on top, give me additional equity for the end-of-lease vehicle due to low mileage and excellent condition, so the monthly payment for a loaded 2004 330ci (MSRP C$58k) virtually the same as a 2003 6MT-C (MSRP C$7k).
Still undecided. Will take a short cooling break and retest the 6MT-C more extensively.
