stupid answers to stupid questions.

Looks: they're all ugly
Motor: they're not driven by electricity
Suspension: they all handle like shit
reliability: extremely unreliable

but seriously

looks : is a matter of opion. different people have different tastes.
motor : why the fuck does it matter if you're planning on doing a swap ?
suspension : the swap you're planning will damage the handling. but it probably wont matter since i doubt you'll be doing anything other than drag racing it (don't reply with that "I was actually planning on autocrossing / road racing it" bullshit).
reliablity : again, why the fuck does it matter if you're planning on doing a swap ?

why dont you swap the ls7 into the 350z in your avatar ? Im sure it'll improve that car in every possible way.
