You don't need spring compressors to do the struts on that car. Just jack stands and hydraulic floor jack.

I didn't think the springs needed compression. Seems like a regular shock replacement but a strut. Just like my 300E. I think he will be happy, save him a bit of cash too!
I have my eye on a 98 SL500 for me as well, soon as I get rid of the Volvo c70 Cabrio.
