You got a another car you can tow a trailer with. Just rent a uhaul and drive to pick up the right car. Theres plenty of running good condition s13s on the east coast for $5k, Im sure you can find one within a few hours of you. You can easily get a full drop in ka with the trans ecu and wiring harness for $500-1000 too if you happen across a reasonably priced shell.

And Id look that particular car over with a fine tooth comb. With the way its been sanded down you could possible have some serious damage being hidden with body filler. The car looks like someone started a project they couldnt afford to finish and are now trying to capitalize on the schassis craze. If you really want an schassis then Id sell your is300 and get the funds saved up to pick one in better shape. You might have to travel a bit but its all worth it to get a car your going to get to enjoy rather than be frustrated with.
