I dearly miss my 1M, but have the M2C coming soon. I'm happy I had the chance to own one. And that being said, I probably won't pay the premium again to buy a 1M when I can have a new M2C at MSRP for the same price or slightly less.
Going M2C for a few reasons, but mainly that BMW is doing this familiar thing where they take M goodies off the M3/4 and stuff them in a smaller package -- and that reminds me of the 1M.
Did I mention I miss my 1M? Every day!
