@3literpwr - Funny how these cars rust depending on how they were taken care of. My door jambs are fine, but my rear seat area is a mess. Yours looks solid. Nice build!
@sugarwood - It forms a rotisserie in that the car doesn't spin within the rotisserie but the entire cage will "roll" over and lie on the next flat spot. In that pic I have it tipped over and resting on the ramps. The car is light enough for 1 person to tip it over. I used Restoration Design's plans. It is a pretty simple build once the pieces are cut. You can see the plans, pics and a short video of it here:
