New to MB Diesels and am looking for input.

Looking at a W115 300D with 133k on the clock. Redone upholstery and the only rust I can find is under the front driver's headlight and the battery tray. Floorboards and trunk look phenomenal!

So the rear doors don't open due to door locks that won't disengage, a couple windows won't roll down along with a non-op sunroof. Seems to be a fuel leak from one of the injectors, the power steering is nonexistent, along with a possible dragging brake caliper since it dives to the right under braking.

I think we can pick it up for around $1000 and the body is VERY clean along with a great interior.

Is it worth the trouble? Is it up for daily driver usage?
