I have a 1989 300te...stock wheels. I want to pick up a set of wheels for my snow tires. I went to e-bay to see if I could find a set of used wheels. What size do I look for? What other model MB will be the exact fit for my car? I have a set of snows that are NOT on rims, but they were on my stock rims. SO, I must get a stock size to fit the ALREADY owned snows.
