FWIW, one of our auto mechanics suggested we sell a vehicle out of California. Said we'd probably get more for it and the buyer wouldn't have so much hassle outside of the state. I'm not sure you'd get much more in Florida for a 55 year old vehicle, and you'd need to figure out if the extra cost of driving it or shipping it would even make it worthwhile. For us, we are towing one of our vehicles (on a 4-up car trailer), but obviously, that's not really a solution for a motorhome.
