Are you kidding me!?!?!?
You want ideas for your car? Just open up an import magazine and those are ur limits, which are none. Here is what i would do to make my car the $hit.
~~~Custom interior including a Fiberglass dash and stick a 12" LCD monitor where the passenger airbag is
~~~ Molded bodykit (LL Inspiration there

)
~~~ 3-Piece 19" rims
~~~ Custom turbocharger
~~~ Shave all the handles, and more off
~~~ 1 Piece headlamps with Porsche xenon lights
~~~ Custom fiberglass trunk setup with an airconditioner in the trunk and an amp rach that spins. Also a fridge (LS430 inspiration)
~~~ Red/Clear Taillamps
~~~ Custom paint job
~~~ CF hood
~~~ DV8 engine swap
~~~ dual exhaust
~~~ Briefcase in the back with $100k to flash at the haters.
Did that cover it? I didnt really go into that much.
