I was looking for exactly the same idea. Small car, less than 10 ft, weight around 2500 pounds or less. Three cars come close - Smart Car, Toyota Scion IQ, Fiat 500. Smart car $12,000 drives like******because of it's clutch-less manual (and feels unstable above 30mph. Fiat is the nicest $18,000 but slightly too heavy. That leaves what I believe to be the perfect Toy Hauler car the Scion IQ. It drives fine on the freeway, weight is right in the acceptable range, fun to drive too $14,000. I drove all three and pick the Scion IQ hands down. Also, check out the Outlaw Class A, it is car carry capable.
