I have always opted for a flatbed. Mainly because I am not crazy about tilting the car either way and running the risk of scraping the ends... Two scenerios for me have been rescuing and relocating. For rescuing, AAA will send a flatbed if you request it. I have the premium coverage and this is included. For relocating, I was able to rent a U-Haul flatbed for not much more than their car dolly...
