I am in need of a coil spring compressor for my 89 420 SEL. I would rather not spend $500 - $1000 to purchase and am looking for some advice on renting one. I have called around our local automotive parts stores and found NAPA and Autozone each have one (by their description) that would work. Many of you have cautioned purchasing or renting certain types of compressors for their lack of safety when used on a Mercedes vehicle. As this is a great concern to me, I would appreciate any advice on these two options as well as possibly renting one from Performance Products/some other supplier.
