I know different parts of the country have a definite bearing. Like on the '91 190e it's not in the kbb. It only goes back to 1992. In the nada under classic you can get a price. It shows 4,050 low retail, 5625 average retail, and 7050 high retail. I had put mine out there for 4750. I didn't get much attention, until a lady that drives a MB sports car saw it. She just had to have it, but I am not exactly for sure her intent? Then I noticed peachy start at 4650 on ebay.
