Whoa there...
Do you have any idea of what you may be looking for? An SL? Well, that's a wide range of models over a long period of time; here, we focus on one: W113. 230-250-280SL. They are the same but very different.
Are you sure you are up for a project? How deep are your pockets?
You may consider narrowing things down a bit, and that may take some time if you are new to Mercedes and new to this model...you may decide you want something older or newer.
There are plenty of SLs available in many places; only a few here.
