1978 Mercedes-Benz W123 from Ecuador


The car had a few electrical problems, the gasket blew (2 times), the overhead cam had to be fixed, there were some holes in the heating system so the dash had to be disassembled. Finally the engine died and the replacement parts cost me a fortune.

General Comments:

Beautiful car, solid, but you should only have it as a second car. No way this should be your first or only car, after all, it is 30 years old. Great for taking it out on the weekend, especially the ones with sunroof.

Would you buy another car from this manufacturer? Don't Know

Can't tell if your problem is generic to German made autos, but the BMW 740il that I own has some of the same problems. My next car will be a GM or Ford...dwa.

I have a 1981 230ce. Every day it drives and no problems.

Also in Ecuador, I just bought my 3rd W123. Something I have learned is not buy the cheapest one, take your time and buy the best you can get, and do a long and good examination before you purchase. I use it as a daily driver, and really enjoy the high torque of the engine and the sunroof. LOTS of DIY work, but I think it is worth it.

The way all cars should be built, the Classic Mercedes-Benz way


Really nothing has "gone wrong". Just normal maintenance.

This is an amazing car, it never dies. I love the smooth ride and comfortable interior.

Mercedes Everlasting Car


Everything I haven't driven the car since 2002, The best part is that I started it up this year 2005 and it runs smoothly. with 785,955miles. Mostly the car's interior is okay shape and the exterior needs a paint job badly, I have never got in a accident since I bought in 1978.

General Comments:

Even to this date this car will never give up with 785,955miles.The paint is very bad becuse I haven't start this car since 2002, but this year I just put the battery in and turn the key and it still started like when I bought in 1978. I took it around the block and on the freeway for 30mins and the car runs like brand new even if it doesn't look like brand new.

To the two wise-cracks above: It is common for people who own older Mercedes models such as this to keep them almost forever. These cars have that certain "something" that draws most owners in and never lets go. When this person said that everything went wrong, they were not joking I'm sure. He probably had the engine rebuilt at least twice and I'm sure most other items on the car were replaced several times. Kudos to him for keeping this classically reliable, but miserably slow automobile for so long and never tiring of it. I can say that because we owned one for many years and I can say it was one of the best cars that we've ever had.

Something that must not be ignored just because it is old


Basically, nothing has gone wrong. The car is well over 20 years old and the only problems I had are due to old age wear.

I had to replace the head gasket as there was not much left of it. I also had the head reconditioned at the same time.

I had to replace the seal in the water pump.

I had to replace the diaphram in the vacuum pump.

All suspension bushes are slowly being replaced.

General Comments:

The W123 is a classic car like all the rest of the models. Nothing can compare, even late model vehicles just don't feel as good to drive.

I found the ride to be a bit to soft, but then this car isn't designed to go fast, it is more of a tourer.

I personally feel that the motor revs to high (up to 5100 RPM), but a slower reving motor from that period would probably vibrate to much.

I like the car so much that I have just bought another one for parts, but it is to good to strip so I will have to rebuild it.
