Top racks are nice for keeping the rear hatch free, that is very true..
But they a pain in the ass getting them up there and down without dinking
the roof or doors etc with the pedals/frame etc as you take the off and back up..
If you are planning on this biking being an infrequent thing then OK,
but if its an every week thing, just imagine the chances of a scratch/ding on your vehicle .. Heck, I've put my bikes in the Pickup bed dozens of times fine, and then one day I slipped and scratched my bed side loading them..
