Your idea of a clean car

my .02$...

straight body, no dings, no scratches or swirls in paint...
tinted windows, no bubbles in tint, no mirrored tint...
no emblems, no stickers... no antenna either...
lowered, but not slammed...
aftermarket wheels... not wire wheels tho... and they have to fit within the wheel wells... no mud flaps stickin off the sides...
nice system... but not one that you feel from blocks away...
spoiler/body kit... but no four foot carbon fiber wing...
speaking of carbon fiber... no fiber hoods that aren't color matched.
clean inside and out...

it doesn't hurt if the car will launch into a low earth orbit either(i just mean be really, really fast, not bounce like with hydraulics)...

but then, it has to be meticulous under the hood... look stock or better than stock... and fartcan mufflers are definitely a no-no...
