Hi,
You must have the twin to my '87 300E. It just turned 180K and there is not a mark on it. I am the second owner and it has been garaged all of its life. I even have the original AC compressor and it blows like a ice blizzard. I am not sure, but it may have the original windshield wiper as it is a desert car. The interior is spottless and it still looks good in the parking lot at the mall.
