Small vehicle to tow behind a Class C

I've towed a Subaru for many years. Its very easy to tow, hook it up, put it in neutral, set the ignition to 1 or 2 depending on whether you need power for your brake box, and go. As Butch50 said, only the manual transmission can be towed.

If you want a really small car, I see several Smart Cars being towed.
