What are some cool looking car racks to go on top? I have seen a few cars that had just awesome looking racks. They had writing all over them.

I've got 2 Yakima Vipers with the Yakima fairing. I think they look good.

You don't want your bike rack to steel the show. You need to showcase your bike instead....

Why put the writing on the racks? They have so little space on them. Save the space for the bikes and just put the writing on the car itself...

Hey, those are some really nice bikes on that car. When it's stuck in traffic or at a busy red light, run up with a screwdriver and...

When you say "cool looking roof racks" I'm guessing you're referring to the ones that many bike shop owners have. You know, the ones with all the stickers and decals on the fairing. Some of them are "cool looking" without any bikes.
If that's what you want then become good friends with the folks are your LBS.

Given that it's a support car, I'll bet there's a special handle you just pull and the bike gets ejected into position on the road. I'm always amazed at how quickly the sag crew can do a bike change.

Yep, that's exactly what I am looking for!
