I second Allen's opinion. IMHO, Yakima makes one of the best roof racks, and we don't even sell them at my shop (Work for a local bike shop on the weekends). Key thing to keep in mind with a roof rack; It will kill your gas mileage (highway) even if you invest in a fairing.
Saris makes a beautiful composite rack that works on the trunk (And it will clear the spoiler IIRC) that's easy to get on and off with just a couple straps. Personally, I really don't like lifting my bike over my car... one day that mud is going to make me slip and *WHAM* there's goes the finish on the roof or a window or something.
