Has anyone had experience using one of these rotisseries? Is it worth it to spend extra to get the hydraulic version? I'm getting into car restoration and thought it might be useful to have if not this particular rotisserie, one similar to it. I'm open for any suggestions.

That's very similar to the one my father has. Don't do it without the hydraulic rams, though the hand pumps are fine. You don't need to go nuts and get the ones that raise/lower at the flip of a switch. Naturally, the PITA is getting the body on and off the thing. I'd recommend using a crane of some sortwith a body harness tailored to your car to lift the body off the frame, then bolt it to the rotisserie. Don't do what we did - jack the body up with bottle-jacks, roll the frame out, lower the body on jackstands, and bolt to rotisserie.

If I get one of those, can I BBQ chicken as I drive?

I could really use one of those...

I built a body dolly for my '59 Buick and mounted the shell on that; there was enough room to roll underneath it from any side while on a creeper, and I could sit upright on the creeper under the rear axle area, and easily reach the rest while laying down. I wire-wheeled the entire underside, welded rusted areas, and painted the underside 2 coats this way.

I would've liked to have had a rotisserie, but the prices for ready-made ones were more than I wanted to spend. I suppose I could've built one of them myself...
