As Tony said, small cars have issues when breaking hard. I know a person who pulled his glider with a Jeep Wrangler and the glider trailer (and glider) ended up rolling sideways down the freeway one afternoon. Very sad.
A long wheelbase is your friend. IMO, the longer, the better for safety. My truck is 140 inches compared to a Rav4 at 103ish. I would never consider using a vehicle with that short of a wheelbase. That is an accident waiting to happen.
