I would recommend the hitch rack carrier from Yakama.
Easy mount, unmount and secure.
I found that the roof carries are way too much work to mount and unmount plus the height limitations.

Yakima DoubleDown 4 Bike Rack from Backcountry.com

I found the customer support and service at Backcountry top notch (worldclass service) at the same worldclass service as Invision Industries (rear DVD entertainment systems), they will never stop until you are totally happy with the product.
