Description for Mercedes-Benz 300-Series 1987

This is not my daily driver, take it whenever I go out of town...I had a new Pioneer CD player put i, ut if you want to put the car back to original, ou can have the original Becker cassette player. (it doesn't work) The antenna goes up when you turn the car on, nd down when you turn it off. The sunroof works great, oesn't leak at all. OK here's an update since I listed it last week. I put a new AC relay in it and the AC started working, ut it wasn't as cold as I thought it should be. I took it to a friend who is a licensed AC tech. to see if he could make it colder. Before we could pump it all the way down, is pump failed. We got it to read 49 degrees at the dashboard, ut now it won't turn on without putting a wire from the battery to the compressor. He said something about a pressure sensor, ut I don't have time to fix it, just want to sell it and register the van I just bought. I had 33 people watching the car last week, aybe the AC not working was a dealbreaker. I wish I hadn't even messed with it after I put the relay in. Now it's cold, t just needs ??? I knocked $500.00 off both the starting price and the buy- it- now. If nobody buys it this week, 'll sell it locally. I know these cars are popular with the biodiesel crowd, nd this car would be a perfect candidate for that. The key locks and unlocks all the doors and the back hatch if you use it in the driver's side or the passenger side. The key doesn't unlock the back hatch for some reason. The glove box works perfectly, nd so do the power seats, indows and steering wheel adjustment. Last week I popped the hood open, nd the end of the cable came off at the lever inside the car, o now I have a small pair of vice grips on it. Hmm what else. I don't think the rear defroster works. Since it's a Florida car, 've never used it anyway. I put some filler on 2 small spots by the back window.You can see in the pictures.There's a rust spot starting just behind the front passenger wheel, ut I didn't get into it, just thought I should mention it. The dashboard has a light for the antilock brakes that turns on and off at will. I asked the doctor that sold me the car about it. He said something about a sensor on the wheel. He never bothered getting it looked at, o neither did I. The brakes work fine. If you have any questions, lease contact me. I have a 100% eBay rating, 'm telling you all I know about the car. I love the car, ut I need a van! Please come look at it if you can, t's being sold in AS-IS condition! Thank you for looking!
