My plan would be peugeots Diablo red, Focus Hella Projector style headlights, ST200 alloys, dropped 35mm, with normal Ghia Foglights, quiet exhaust but with a nice tailpipe, fully colour coded and a slight tint on the back windows. Proper OEM+ sort of thing.

Interior would be dark wood centre console but converted to single DIN, trip computer, ST170 half leathers and some lighting trickery with the door handles and what not.

But the fact I'm thinking twice is enough for me to say it's probably not a good idea
