To be realistic:
A Honda civic'ish style as a coupe, 250 BHP, 4wd, Factory exterior/inteior tuning, Evo V spoiler and front bumper, Kia Koup rear deisgn, Evo X grill, 09 Impreza STI exhaust design, and Evo VII hood, and BBS CV rims as stock.
To go OTT:
Get a Bugatti veyron with a Restyled RX7 veilside bodykit to fit on the Veyron, a Focus RS wing on the back, with HRE Comp93 wheels stock.
