Although, it wasn't a stripper as I was originally looking for, it was nice to jump right in and hit the start button with Comfort Access and have all of the bells and whistles that I have grown accustomed to in my M3.
I don't have any regrets on the specs on my M3, it was what I wanted at the time. And now it just isn't what I want anymore. If I couldn't land the 1M, I would have certainly gone for another M3 with 6MT.
Ultimately, the switch to manual is the most significant change.
You need to do a comparison writeup at some point (once you've had enough seat time). For what it's worth, everyone has said the MT in the 1M is much better than in the M3. I've driven the 1M once and it seemed nice, but didn't get to drive the car hard or long enough to make up a solid opinion.
