The real answers are:
1. Mountain biking friends don't let mountain biking friends buy racks where you have to take the wheels off. You can help this by selling what the dealer gave you as "mint" or "as new" ASAP.
2. Get a hitch rack. Mountain bikers should be doing their air time on bikes, not lifting bikes in the air on cars. Note that real hitch racks for mountain bikes hold the bike by the wheels and not hang on a bar.
3. If you ride a lot and appreciate engineering friends only let friends by a 1 Up.
4. If you're not so serious or just can't afford it Saris offers absolutely superb life time warranty support on well designed racks. Saris Freedom is barely more than $200 and very light weight which is nice for cars.
Good luck.
P.S. I confess to occasional carriage on roof and for that use the type that holds by wheels.
