My .02, is keep looking. By the time you address the issues that you listed you will be in DEEP
. The big ones for me are the water in the trunk, the AC. Each of those issues can turn out to be $$$$$. For $3k, you can find a really sweet 123 if you are patient. I wish I new of this forum prior to my purchase (first MB diesel). I probaly would have passed. But now, one year later after much blood, sweat and tears....and cash. I would no sooner part ways with my car than I would one of my children. I guess what I am trying to say is, you WILL pay when you purchase one of these it's just a matter of doing it up front or the "installment " plan. Good luck!
