Morganism

I've been searching around the forums and the internet and haven't found a solution to this, although I was expecting it to be relatively straightforward. When you create spring constraints between dynamic objects, it looks like it's only possible to have them connected at the center of mass. So what is the best way to get multiple springs attached at different points to an object, such as a plane suspended from its corners? A common example is simple vehicle suspension, where you'd want the chassis to be spring-constrained to the wheels at 4 points.
I'm not super familiar with dynamics, my failed attempts include creating an extra rigid object for each contact point, but I haven't found a way to connect them so that the parent (chassis) affects and is affected by the spring dynamics. All my experiments with multiple nail constraints have had very unpredictable results.
I guess there may be a soft-body solution, attaching springs to vertices, but I'd prefer to have the output be rigid if possible, so that I don't have to do a geometry constraint for other driven objects.
Any insight?
