I agree, it's a cool looking car, but for that price, I could buy a bangin' dually pickup and pull about anything I wanted and not be afraid if I went across a bump, I would drag the bottom of the truck off.
If that car is as described, it shouldn't be towing anything.
You could tow 4,000 pounds-5,000 pounds with it, but why would you? Its a show car, and its not built to tow. The suspension and brakes would not be up for it. You need a brake controller. Bad idea. The car is worth more than a diesel truck.
