I have a 1979 300sd for sale in Everett, wa. I've had it for a few years but it's time to sell. It runs, drives and stops fine, the turbo kicks in and seems to work fine. The engine is a strong runner-it does leak oil. It's probably described best as a running parts car. The bad-the front power windows don't work. I had the internals on the driver side replace a few years ago and it worked for probably a year and quit-I haven't tried to see what the problem is. The heater blower motor works off and on, so It probably needs new brushes, the rebuild kit can be found online. no body damage. I'm asking 500, I'm firm on the price as I can donate it and get more than that as a tax write off-but I know it'll be sent to the crusher if I do that, so I thought I'd try to sell it first.
