I build rotisseries in Canada for the market up here. I've made it a point over the years to look at all of the higher end (US-made) units and my favorite by a long shot is the Whirly-Jig. A little more money maybe but better than anything else by leaps and bounds.
Here's a prime example ... this unit doesn't even have a car on it and its already sagging at the ends of the arms !!! And this is their top of the line model !!!

My other problem is I put a 70 Challenger convertible on it and can't get it perfectly balanced no matter where I adjust it. I was told the lower center of gravity of a vert makes it tough.
This is absolutely true of convertibles. To get them to balance well you need mounts that raise the car up a bit. On ragtops the car has to be able to be raised so that the floor is almost level with the pivots!
