Relax... I don't think you got a screaming deal and I don't think you got ripped off. You got a gently used Benz should (If the legend be true...) give you years of service.
I also think you have the desirable engine.
Sad that power windows were crap back then And the whole ACC thing was a debacle...
Mine has 97,000 miles and rolling. I think... I have one that shows 220,000 but the speedometer has been replaced. It's pretty solid but has a lot of negative camber in the rear. The alignment tech says that there is no adjustment so some bushings must be worn.
I Flew about 500 miles and drove mine home! Is that faith or stupidity??
My AC is working for the moment. Mine was blowing cold near Miami but when I changed it to defrost it decided it liked that setting and stuck. It was pretty hot in the car because it was still blowing hot air out the defrost ducts. My engine also decided not to turn off about this time. I ended up pulling the AC fuse to stop the blower from running. I think I turned the AC button off and put it on hi cool (I think) before replacing the fuse. Now the engine will shut off so I believe it's a vacuum leak in the AC system. I haven't touched the AC buttons other than the AC on/off switch. It controls the compressor and I just close the dash vents manually. The blower runs with the ignition on.
My temp gauge is also out which is my next project.
It is doing some strange things electrically... I had no glow plug light (and possibly no glow plugs working ) until tonight. Seems to have fixed itself. My headlights were coming on with the ignition like daytime running lights but that stopped when the glow plug light came on. I'm doing some suspension work as well. Waiting on parts...
And I do enjoy driving it! The performance seems to be getting better and better the more fuel I run through it. I pegged the speedo today
but I don't think it'll be doing that a lot! It felt pretty solid at those speeds and seems to "want" to cruise at about 70mph. I'd also like to have a 120mph speedo but I'm about spent out on the car for now. I did drop a car payment though
so there will be some money for fixing other things. Insurance dropped as well...
