1976 Mercedes-Benz W115 300D diesel from North America

Summary:

For a 35+ year old car, this Mercedes puts newer cars to shame in looks, reliability and performance

Faults:

Water pump needed replacement. The seat supports are due for reconditioning.

General Comments:

This car is a true testament to the reliability of the Mercedes diesel marque. The 115 handles beautifully, and accelerates just like a gas powered car. It gets excellent fuel economy, and is extremely reliable on the highway for long trips. I went for a long trip towards California, and this car kept up with the 2007 model Porsches and BMW's on the highway, and at 120 km/p/h, the car was solid and sturdy like a tank. The engine purrs like a kitten, with minimal noise in the cabin.

The Mercedes W115 is roomy and very comfortable, with sofa like seats, and lots of leg and headroom. A beautifully crafted interior, the W115 has a very inviting cabin. The ergonomics on the dashboard are excellent for the time period, and it has really good heat and cool air. The air conditioner is very powerful and blows ice cold. The trunk has ample room for luggage and more.

This is an awesome car. I would recommend the Mercedes 300D W115 to anyone!

1976 Mercedes-Benz W115 300D 5 cylinder diesel from North America

Summary:

The best car Mercedes ever built

Faults:

Transmission has started to shift a little rough on occasion.

General Comments:

This car is an incredible piece of work. A pleasure to drive, accelerates very quickly, and is in excellent condition. The car handles like a sports car and has an incredible turning radius.

The car is built like a tank, and is arguably the best design Mercedes styled for a 4 door sedan.

1976 Mercedes-Benz W115 240 d from North America

Summary:

It is great!

Faults:

The air conditioning is not blowing coldly. I don't know what to do to get it working correctly. I also, have notice that the back seat is rusted and the fuel gauge is not working correctly. Also, heat comes from the engine to the feet area. But, besides these minor issue my baby Vanilla Ice is running great!

General Comments:

I love my car as it makes me feel very important when I drive it. I make my car look so great when I step out of it.

1976 Mercedes-Benz W115 240D 2.4 from North America

Summary:

Wonderful car, would like to fix the smoke screen problem

Faults:

Nothing has gone wrong yet. I just purchased this car from the original owner in Grand Junction Colorado. It seems to run great minus the fact that it blows more smoke than any car I have ever seen. Think "Uncle Buck" this is that car. I really am looking for any advice from anyone who might know where to start. Acceleration is typical black, which is ok. The second I let off the pedal it starts pouring out white and sometimes blue. At idle it runs high and just belts out blue smoke!!

The car is mint other than this annoying problem.

General Comments:

Love the car for the price runs great other than above problems.

In general:

-blue smoke = car consumes oil; for instance when O-rings and/or valve stems are worn

-white smoke = water (sometimes due to condensation) in the mixture; for instance when the head gasket is gone

Hope that helps.

Hi, I have a 71 220D that does the same thing- I have been told it is a problem of the diesel injection pump-I live in Oklahoma City and it won't start if temp falls into the high 30's- I am looking for suggestions, as well- I love the way the car rides and drives- it actually runs good except for the cloud of black smoke- it also puts out a lot of blue smoke on a cool morning!! Thanks and good luck!!

1976 Mercedes-Benz W115 300D from North America

Summary:

A great car, but expensive to repair

Faults:

Major rust problem.

Rear bumper fell off (on one side.)

Heating/air-conditioning control unit had to be replaced. -- a thousand bucks!!

Burned a fair amount of oil.

Muffler system had to be replaced. -- a thousand bucks!!

Rubber fuel line sprung a leak.

General Comments:

Had rust coming out all over on the body shortly after I bought it -- thankfully, it has a body built like a tank...

Overall ran not too bad, but was terrible at starting in the winter. In spite of using the glow plugs, I still had to fire up the hibachi under the engine on numerous occasions.

Took a while to get used to the slow acceleration...

All parts were very expensive. IE: The price one has to pay for sitting on luxurious chairs in the fancy dealership's waiting room...

The rear bumper, made out of cast aluminum, was terrible. Any salt on the highway eats this aluminum, thus one side of the bumper fell off. bolted it back on by riveting a power saw bar to the inside of the bumper.

A lovely vehicle to drive, and very comfortable.

Try to get the European bumpers. They are made of chromed steel and looks much nicer. I don't know if they are easy to find in the USA though...

14th Jun 2005, 10:26

But aren't American 300D Mercedes bumpers like 10 times the size as European bumpers and much safer.

4th Oct 2005, 16:58

Yes, European Mercedes don't really have bumpers.

I own a 76 300D, and you got absolutely raped on the repair prices. A muffler shouldn't cost more than $300, and pipes can be fabricated for less than a hundred bucks...

Don't know about the heat/AC stuff, but you should have gotten one from a junkyard...

Also don't go to a dealership to get parts, go to http://www.autohausaz.com/

Good luck, and don't be afraid to get your hands dirty, they're so simple... They lose their "holiness" by the time you've taken the valve cover off, and you're sitting on the fender cover trying to get the darn injector pump out.

I just went to "Parts Plus" in Mineola TX and priced a compressor for the A/C (1976 300D) and it was 167.00.

19th May 2007, 07:15

What is fair price to pay for a 1976 300d in excellent physical condition, but the motor was taken out and sitting in the trunk? The motor did work, but not well.

I completely agree - they're wonderful cars and I was lucky enough to get one at 16 as my first car. Unfortunately I hydroplaned into a Tahoe and left it needing a great deal of body work and a new radiator - the latter is nearly impossible to find, and I'm trying to fix it up now for my father, who has never quite forgiven me for destroying it.

1976 Mercedes-Benz W115 240D diesel from North America

Summary:

One of the best all-round cars I have driven

Faults:

Water pump replaced in 1987.

A steering link rusted away in 1989. Cost $10 to repair.

Glow plugs replaced twice in the last 10 years.

General Comments:

It drives like a tank and don't think about getting one if you need a getaway car. It is slow but steady, and I would think nothing of getting into this 27 year-old car right now and driving a thousand miles.

It's main problem is that in cold weather it requires several Hail Mary's to get it started, but once it is running nothing will stop it.

Mercedes corrected the cold-starting problem in later models, and modern Mercedes diesels start in seconds.

You can pick up a decent 240D for $1000 to $2000. Don't be afraid if the miles seem high - these engines will do 2 or 3 times the miles other cars can do. Just make sure you have a battery recharger on board because in cold weather your battery will need to be 100 percent.

Cold-weather starting in older Mercedes and other diesels is much improved by using 0-W30 weight synthetic oil in the engine (e.g., Amsoil), fitting an electric block heater and/or coolant heater (ideally both!) and using a fuel conditioner. Even without plugging in, my old 240D started down to -15 C, and plugged in, down to around -30. Below that was touch and go... Now it is retired and lives in Vancouver, where it is pushing 350K km.
