But, it also seems like the SLK320 came with a spare - is there any reason why that would not work on a Crossfire Coupe?? Thanks.

There were two different spare tires used on the first gen MB SLK's. The SLK320 (Crossfire Base/Limited) had 16" wheels on those models, but on the MB SLK32 (Crossfire SRT6), those SLK models had 17" wheels due to the larger brakes (discs & Calipers) for clearance. If you have a Base/Limited Crossfire, you can use either a 16" or 17" space saver tire. The SRT6 will require a 17" or larger wheel for fitment reasons. Keep in mind, the sidewall aspect of the SLK320/32 had tires with either a 60 or 55 sidewall as compared to the low-profile tires of 40/35 on the Crossfire.
Another aspect of adding a "spare", is the calculation related to the tire diameter of the rear tire that is currently on your Crossfire. If the measurements are unequal between the spare and the existing tire, that difference will cause harm to the rear differential if the spare is used over an extended mileage use. The fitment on the front end is not impacted by the size difference, except for the ride and steering capabilities.
Unless the spare comes with the shorter lug nuts, they must be purchased, since the spare is a steel wheel vs. the cast standard wheels on the Crossfire.
Do your research, to confirm fitment before you buy a spare....
Good Luck....
