To me, it's all about what colors I have/have had for the last so many years. I currently have a beautiful magnetic red car (13 years), a white MX6 GT (17 years), and a Galaxy Grey Mica MX5 (1 year). I know lots of people prefer neutral colors, like black, grey, white, or silver, but I prefer colors that stand out, like reds, blues, and greens. However, since I'm tired of red, that leaves me with blue - blue reflex or deep crystal blue. I will keep it covered during the day (car cover), so darker color temps don't concern me.
I see that some dealerships are offering 0.9% financing on 3s.(cool)
