I purchased a 2008 BMW M3 Convertible with the DCT transmission two weeks ago. It has all options except extended leather and parking sensors. This car is amazing. It's ridiculously powerful and fast. If you feel like being an F1 Driver, you can shift with the paddles, if you're feeling lazy (or commuting), you can just put it in "D" mode, and let the DCT do the work for you. With the convertible hardtop, the car is quiet and rattle-free. The stereo is excellent, and the seats are very adjustable, supportive and comfortable.
Drove a 2009 Porsche 911 with A/M before I drove the M3 6spd. The 911 didn't impress me. The M3 blew me away. Got it will all the options and brushed aluminum. It is very comfortable. Takes a little time to get used to shifting the manual. You can tell a major difference from M mode and regular mode. Fuel economy is almost the same in both so I usually just leave it in M. In M it is a rocket, in regular my 4-runner accelerates faster. Icontrol is easy to use and they seem to have thought of everything and put it in the right place.
Just brought my new 2008 m3 cab home. Traded a 2008 P 911S cab. The M3 is faster and tighter with 19s and M drive. I am really juiced. Have had a 2007 P911 turbo, a bmw 645, and another P911S cab in the last 4 years, but this seems to hold its own with the turbo and beat the rest. More comfortable the the Porsche with incredible handling. M3 has satellite radio, something Porsche did not offer until 2009 and then at a very steep option price. And my insurance went down to boot!
I always considered a convertible M3 as my dream car and in 2008 I went out and bought one- brand new. It was gorgeous and "impressive" but totally and absolutely not worth the sticker price. It had so many stupid quirks that I rarely drove it, preferring my Volvo station wagon (!). I will never again buy a BMW and I pity the poor guy who got mine when I dumped it after 2 years and only 15,000 miles. I'm glad I got the BMW bug out of my system, but it cost a lot to be cured!
I have always wanted a M3 and with the introduction of the new M in 08' I couldn't have picked a better time to get one. I decided to go with the hard top convertible to get the best of both worlds. True coupe like design and then who could argue the experience of open roof driving. I have invested in an amazing performance exhaust because I was a little disappointed with the stock sound... no way did it sound like a V- 8, but it sure does now!! I also put H&R Sport lowering springs on it to give the car an even more aggressive stance at stand still and it corners even better now... if you can improve on the amazing handling it came with.
