Yesterday I had some paintless dent removal work done to my 91 940. Below are two pics of the front right hand side guard (fender) on my car. It's a little difficult to tell but the dent is all but gone. There is only an extremely slight imperfection in the panel which you wouldn't see if you didn't know it was there. There is also a small scratch that gives a clue as to where it was. I had five dents removed from the car (none of them done by me) - the one shown here was the worst. It's impossible to tell where the other dents were.
Total cost was $330 (Australian) and about two and a half hours time. Cheaper and quicker than having it done by a panel shop and it retains the original paint. I'm very happy with the results.
