These cars look awesome in pretty much any color/trim combination, so I'd go for whatever takes your fancy. Black roof always adds to the look too, but you could do that later. The only option I got that I probably won't do next time are the power seats - I've once used them!Did get the CF backs tho' and they match the CF dash nicely.
Make sure the car has had all the recalls and upgrades attended to, and if its a year old get the service done as part of the deal and save yourself $1280. I'm sure there's an official list of upgrades and recalls somewhere, but there has been a LOT! Door latches, A/C, V-10, suspension sensors, amplifiers, etc, etc.
Do it now Boxer!!!
