First of all go to Remco.com and plug in the type car you want to tow and you will get a pretty accurate answer. Many vehicle manufactuers automatically exclude their cars from towing as a matter of liability.
As for me I have towed several Hondas, some stick and some auto, presently I am towing a Chev HHR with auto. Some what of a Geezer mobile but works for my wife who is handicapped and can't climb into taller cars.
Can be frustrating just make it part of the RV lifestyle.
