What country do you live in and what model are you looking for (ex. 3s vs 3i in the US)? Your choices depend on these things so let us know so were not suggesting things that aren't even options for you. Are you planning to get leather? If not, consider what color interior cloth seats you'd prefer too since this is dependent on exterior color. I dig the blue/black. Do you like keeping things looking clean and waxed or do you let your car go for a while without a wash? If the latter you probably don't want my Strato Blue or black for that matter, but silver would be a better option.
