buying a 1967 mercedes 250S..what should I look for?

This is the first time I am purchasing an older car, and I'm looking to buy a 1967 mercedes 250S that I have found. I was hoping for advice on what I should be looking for that may be wrong with it. I have already found two patches of rust on the front fenders, and the car ran before, but has been sitting for the past 2 years so it currently does not run. But is there anything else that you would recommend that I keep an eye out for? Thank you!

I have a '67 250S that my Dad bought new. It has been garaged and well cared for since new. They are relatively trouble free, basic automobiles and will give good service, IF PAST MAINTENANCE HAS BEEN TIMELY AND ADEQUATE. If they have been neglected or adversely tampered with, they can be relatively costly and time consuming to repair. I've had mine since my Dad's passing in 1991, and here are the problems that I have repaired or need to be repaired. Most are normal wear and tear common problems found on any vehicle.
1. Fuel pump. Easy to either rebuild or replace.
2. Spark plugs, wires, distributor cap and rotor.
3. Rear pneumatic shock on rear end (not shock absorbers) fail. Get a spring replacement and it will never have to be messed with again.
4. Driver's window regulator. Make sure all windows go up and down smoothly, and relatively effortlessly.
5. Brakes, calipers, brake hoses. Easy, and inexpensive to repair/replace. I had an old hose collapse on brake release and it would not fully release that brake.
6. Heater blower on all speeds. Make sure it works and does not make noise. Mine is bad, and this is probably one of the most major jobs on the whole vehicle. I haven't tackled mine yet.
7. Heater control valve. A pain to overhaul and fix, just time consuming.
8. Clutch unit for the cooling fan. Easy fix, expensive to buy.
9. Radiator recore. Expensive to have done ($450) and many shops say they can't do it keeping stock configuration.
10. Timing chain tensioners and guide rails. This is a pretty good job, and that's why I haven't done mine yet, but it's on the list.
11. The dual Zenith carbs. can be a pain if someone has screwed with them. Fortunately mine have never been tampered with and work great. I have had to replace one brassfloat that started to leak. They are the same floats that go in the single throat VW bug carbs. Dealer cost about 15 years ago was $45each. I got two used VW ones for $5 and it's worked ever since.
12. I had a rocker arm ball socket fail (crystalized) in the middle of the desert. With the stock factory tool kit (see if yours comes with it) I pulled the valve cover to see the problem. I pulled the spark plug for that cylinder and drove it over 200 miles on 5 cylinders until I got to a place that I could get parts. If I had been unable to get parts, I was prepared to drive it all the way back home, which was another 400 miles. In preparation, I had a gutted spark plug welded to a lawn mower muffler to quiet it down. Finally found the parts though.

Beyond that, just check the normal items and try to ascertain whether or not it has been cared for or not. If it's just normal wear and tear, and you're relatively handy (don't have to pay someone to fix everything), I'd go for it.
Bare in mind that these things are slugs at best, but once they get moving they are pretty nice cruisers. I still get lots of looks and questions everytime I take it out. Good luck and let us know what you decide. There are plenty of folks on the forums that can guide you along once you purchase one.

If you want to buy a 250S make sure you know somebody who can handle a carburetor,if you show it to one of these new young mechanic they will not even recognize what it is.

thanks a lot. thats extremmmely helpful. its funny that you mention the drivers window regulator, because the drivers window doesnt move at all and the other windows are extremely touch-and-go. I'm hoping to have a mercedes mechanic look over it to make sure everything looks like its ok, but thats a great starting list of things for me to keep an eye out for. thank you again.

check your window SWITCHES first...

they get gunky, sticky, corroded and "sporadic"...

don't listen to negative statements like you need all 4 window regulators for $800...

he hasn't even seen your car, much less professionally diagnosed your window situation...

with common sense, a little time and care, you should have a great car with minimal expense...
there will be expense, that is a certain...
how much expense???
may mr. mercedes and mr. benz guide and protect you from their aluminum 300 sl roadsters in the sky!!!
but remember, their grandsons and daughters earn a GREAT living from the parts you buy!!!
