I am going to look at a 84 300sd tomorrow, the guy only wants $500 for it. he says the body and interior are fine. the transmission is fine and it starts up but he says it has little power. i want to know what you guys think? that would probably mean loss of fuel right? maybe cloged filters maybe the one in the tank clogged banjo fittings? bad fuel? it is a little bit of a drive so i wanted opinions before i made the trip. has anyone ever bought a car like this and found it to be something simple and it ended up being a great car? oh yeah it has around 195K miles on it...
