Very poorly, I would imagine... even the UV inhibited rubber tends to 
degrade after a few years.  I'll bet there are elastomers that could 
be used, but, there might be a better system solution to taking up 
misalignment, buffering the slings and arrows of shock loads, and 
damping vibrations.  The couplings that look like a spring would do 
the first two.

At least if you keep the greasy side of the car towards the 
road.  Erik "on the roof" Carlsson might have different experiences.
