The best carriers are the tow bar mounted ones, but that means having a tow bar. You will get the tow bar socket for a lighting board tho'. Often overlooked by some people that hang bikes off the back of the car and obscure the lights. Other than that, get them up on the roof out of the way. I have my feet, bars and bike carriers all set up so they can be fitted / removed in a matter of minutes. Probably the same amount of time that it takes to fit my tow bar carrier.
