If you want to tow a car you need a truck designed to tow. Not a big car with 4wd.
I'll sell you my 01 Sierra for 8k today.

My car trailer weighs 1920 and with the car it weighs 5200 and the old 5.3 pulls it and still gets 16mpg. That is after the CAI, headers, exhaust and Hi-Tech. It doesn't squat, it doesn't sway. In fact with the cruise set at 70 you forget it's there at all. I've looked in the mirror a couple of times about to get pissed that some dick in a DSM is following so close.
