Neighbor has an older Mustang "drag racer". Turbo charged, roll cage, but still street legal. Bugged me to buy my 16' double axle flat bed, then wound up getting a used car hauler (two steel areas for the trailer bed, open center). Turned out he was glad he did.
Snapped the driveshaft at the races last fall, crawled under there and replaced everything, since the center was open to allow access.
Use my flatbed to haul fire wood (two+ cords with the 30" high racks on), old tractors and whatever I need moved. Big Tex, 10,000 gross. Pulls very well. Original PT wood floor lasted about three years, exposed to the elements. Usually parked under trees out back, so it doesn't get to dry out.
Replaced it with a better grade of 2x6 PT lumber and treat it every fall.
