Faults:

A lot of things were wrong with this car when I first bought it, it had been standing still in a carport for over 10 years.

After changing oil and fuel it did actually start at once, but only running on 3 out of 4 cylinders. At high RPMs the last cylinder (cyl# 1) starts working.

There a bit of rust, but I've fixed most of it this summer.

The foot button to active the windshield sprayer was totally stuck so I replaced it.

The heating fan was broken and had to be replaced (this was no fun, we basically stripped down the whole car to get to the fan). Its regulator was broken as well.

The plastic housing around the engine broke just a couple of weeks ago. I've seen more W115s with this problem.

The fuel line had a small hole due to a lack of mud flaps.. Also a common problem, can't understand why MB puts a fuel line so close behind the front tires.

The start motor is kinda broken as well, but sometimes it works so I'm not going to change it until I get the new engine running.

The seats are in bad shape (worn) but with some new covers they'll be like new again..

The speedometer is broken as well as in it shows the speed, but doesn't count any km/miles. Sometimes it does, but usually it doesn't.

The clock is broken as well.

General Comments:

Compared to my Volvo 244DL (1974) this car is extremely comfortable! No racing monster, but comfortable.

My girlfriend always want to have it cold and I like it warm so the double heating system is perfect.

The engine is still going on 3 cylinders at this moment, but it's going to be changed soon to a 240D 3,0 engine for some more power :)

I also bought a new generator that will be put in together with the new engine. 35A is just not enough.
