Call Walter's up in Riverside and see if they still have the Cayman R/able to test drive. It is a six speed. They have several GTS' with good options and have heard they will deal. I am a big fan of the GTS and of your list, would be my choice. 117 is not that high for the GTS. They can get near 130 on PDK cars.
You could also take a drive up to Beverly Hills. They have a 6 speed Cayman R too..or did.
The C63 would be hard to pass up but paying sticker and the huge depreciation would have me thinking hard.
Lease or buying? Being you have not had the M3 that long you may want to check both brands lease offers. If you get in and out every few years that is.
