Kina makes you wonder what they were smoking when they did that........I want some :PClementine said:That's a favourite feature of mine. They positioned one rear wheel slightly behind the other to offset the torsion bars. The advantage over vertically offset torsion bars was probably packaging as much as anything.
Doesn't seem to affect handling. And it's amazing how many people don't believe you when you tell them the wheel base on one side of your car is 2 inches longer than the other.
You sent a question about cleaning products. I tend to use interior shampoo to clean interior vinyl, then leather conditioner is very good to keep the vinyl soft. I don't know what you could use on the roof.
