Ok, so I bought a 2004 xfire. She failed inspection for a broken front left coil spring. I purchased a spring set that fit a 2003 Mecedes SLK 320 (R170). I also bought a spring compressor for various Mercedes models. The front spring is the 14 inch spring. On other posts about this subject, part number 05102297aa was for the rear springs but referenced for the front.

So, in order to get the spring out after compression, you have to disconnect the upper shock bolt, upper ball joint, and sway bar end. A second jack helps out to relieve tension on the lower A frame.

Reinstall hardware removed then uncompress spring. Be aware the compression tool gets stuck and some hammering may be necessary.

There it is, spring replacement after 3 hours.
