In the end I used a Lisle spring compressor that actually bolts onto the srping instead of using hooks.

The description uses the words 'super safe' which made me feel better and I have always had good experience with Lisle. You can order these online for around $55 or I bought one locally from Parts Depot for just over $60 but got it that day. This compressor will compress the spring enough for you to replace the bushing with the control arm on the car but is not suitable if you want to remove and replace the spring itself. Just be sure to keep a jack or stand under the control arm while doing this for extra insurance.
The other trick was in flaring the sleeve in the replacement bushing. When you put the new bushings in they are held in place by an aluminum sleeve that has to be flared on the end. The manual shows a special tool and there have been other posts by people using various devices. I had great success using lug nuts from my truck. A lug nut is hollow in the middle and has a cone on one side so I took a long 3/8" bolt with the appropriate stacks of washers and stuck it through the middle of the bushing, slid the lg not on, more washers and spacers as needed, and a 3/8" nut to tighten it down. Tightening the whole assembly caused the lug nut's cone to flare the end of the sleeve perfectly.

It is not spending almost $200 for a spring compressor that is the problem. It is spending $200 for a spring compressor that you can most likely use on only Mercedes.
If I spend that type of money on any tool I need to be able to use it on my other vehicles or it has to be something critical like the Timing Chain Crimping tool.
You can rent but when you buy you have have a tool in hand that you can use on something else. By not renting you can work at your own pace and schedual.
If I can make a tool that will do the same job; why not.
