I would get a SS Maxx with 3.9 and 6spd manual with thoes rims, and dual chrome exhaust! I like the chrome bar across the front though. Everything else looks good, but thoes fogs look a little too after-thought.
It's surprising sometimes what a few minor tweaks can do for a car. The regular Malibu is kinda blah, kinda average-looking, seemed to say "May I help you?". Blackout the chrome and put some big wheels (I'd go with 17"-ers personally instead of those monsters...those are supposed to be what, 19? 20?), lower it a tad, and now the car says "...what the hell do YOU want?!"
Those rims are 18" or 19". In production they would most likely be 16 or 17. Given the way GM likes to leave a little room over the wheels I would suspect any lowering would be done strictly with ground effects. But maybe with a stiff suspension they could get bold and lower it a touch.
