Can anyone recommend a Florida body shop that would be experienced in repairing the rust that develops on the underside of the doors. I am in rural Central South Florida and want someone good as this is the second time I am addressing this problem. The car is a 1993 600SL. I know it will not be cheap.

I've had great results with Dimmitt Collision ind Oldsmar (Tampa)
they do alot of very high end cars as well
good luck
