Description for Mercedes-Benz 300-Series 1982

The time has come to part with my exceptionally clean Black on Black, accident free, low mileage 1982 W126 300SD. I purchased the car in May of 2014 with 122,000 miles on the odometer. Miles were confirmed to be accurate via CarFax. After purchasing the car I spent the next 2 years having it repainted, rebuilding it, refreshing it, detailing it, servicing it and just enjoying the car. I changed the oil every 5000 miles and at the end of summer before putting it in storage for the Winter even if it hadn't been 5000 miles. I only use high zinc content premium oil specifically for diesels.

There is a 30 page thread that covers everything I have done to the car on benzworld.org.

I have loved this car. The car currently has 134,000 miles on it, driven only 9,000 miles since May of 2014. The miles may be slightly higher as I drive the car on nice days. The car has never seen snow and it shows. I have stored it inside and covered during the winter and have always garaged it any other time. The car has been repainted to fix the fading original clear coat/paint. The underside of the car, trunk, floor pans, front spring mounts, jack points, everything is clean and solid. It is very evident that this car was not driven in the winter or has ever seen salt.

The car starts right up and idles with no issues. On colder mornings the new block heater does make a difference but, even at 20 degrees she will fire right up with a single cycle of the glow plugs. She does smoke a little on start up when cold but, does get better as she warms up. The car really is a pleasure to drive. She tracks down the road arrow straight, no shakes or shimmy and can easily cruise all day long at 65 MPH and I have even had her up to 85 MPH on a long stretch of highway and it's like the car was made to drive at this speed. The transmission shifts are firm with no slipping. The cruise control works, all gauges work, and the car is just a pleasure to drive. The car came with all the original owner's manuals and even the original first aid kit is still there. Heck, even the strings are still attached to the cruise and HVAC cards, something I have not seen before.

I have made some nice upgrades to include a Euro front bumper with Euro fog lights, Euro headlight conversion, swapping in GEN II W126 leather interior, GEN II rear parcel shelf and swapped in better wood trim for the pieces that had cracked. The GEN II leather really transforms the car. All the carpets were removed, cleaned and re-dyed.

I've tried to write an honest listing on my car. I am a car enthusiast and am selling her only because I have started another project and just don't have the garage space for two sunny weather only cars. Please, if you want to know something ask. I will send any additional pictures or videos if you want to see something specific. I will gladly help with shipping and highly encourage any potential buyer to come and look at and drive the car, especially being a vintage classic. Or I am even willing to meet you part way if that helps.

Carfax does show an odometer discrepancy and that is accurate and is my fault. When I went to register the vehicle I initially wrote down the wrong miles on the title and scratched over it and wrote in the correct miles. I soon found out this is a big no no on a title. My options were to go back to the seller and get a notarized affidavit stating that the miles were 122,000 at the time of sale or just have 9,999,999 listed as the miles on the title. I chose the latter because I wanted to just get the car registered. The true miles at the time I bought the car were 122,000 and the miles are currently 132,000 and the odometer reads accurately as I replaced all the gears upon my purchase.

I have put a lot of hours into bringing this car to how she looks and drives now. I know you never get back what you put into a car but, I hope I have listed this at a fair starting price and hopefully she will attract a new, equally enthusiastic owner as I have been over the past two years.

I have in hand a clean title and my receipt binder with over $1700.00 in receipts not including the $900.00 it cost for the GEN II interior, $350.00 for OEM Bosch Euro headlights, and $300.00 for the Euro front bumper.What I have done (and much more) since owning the car

  • - New front chrome grill

I will be honest as I do not want any unhappy buyers. The paint looks amazing from 5 feet away but, when you get right up on it you can see imperfections in the paint. I was deployed when the paint was finished and my wife took delivery of the car. I am not too upset with the paint job and it does look nice and shiny from 5 feet and is protecting the car

Drive Train:

- Newer tires

  • - Upgraded 8 hole OEM Mercedes rims. Very straight with no curb rash

  • - Two new flex discs (need to be installed)

  • - New front steering components. Car is tight and drives straight

  • - New brakes front and rear

  • - Transmission and rear differential fluid changed last Fall before putting away in storage. (spare trans gasket and filters included) I had a set ready for this winter

What still needs to be done:

- Stereo and speakers wired

  • - New OEM Mercedes gasket installed in rear window. This will be included with the car.

  • - Rear windows will need to be sorted out. They only work when supplied power directly.

  • - Driver's and passengers door mounted power seat switches will need new plastic internal stalks. They work but will need tidying up.

  • - A/C compressor missing.

  • - Heat will have to be sorted out. Sometimes the heat works down on your feet and sometimes it doesn't. If I were keeping the car I would pull out the dash and rebuild all the vacuum bellows which are normally the cause of erratic heating issues. It isn't the control unit as I bought a new rebuilt one from Programa in Florida.

  • - Dash has a crack on the driver's side that will need to be fixed if you are so inclined.

  • - Window switches sorted out

  • - I'm still looking for a nice shifter surround

Please, ask questions if you have them. I do not want an unhappy buyer. I really have enjoyed this car but, my new project needs the garage space. I highly encourage any prospective buyer to come and look at the car.

My last big trip in the car was a 10 hour trip to New Jersey and back to look at another Mercedes and she ran flawlessly. 80 MPH on the highway was not a problem. The car rode great, not a hiccup one out of her. I truly would not hesitate to drive her cross country tomorrow.

Do understand this is a 34 year old car that has some character but, try finding a 1982 300SD with only 130,000 miles that has been taken cared of the way I have taken care of this car at my starting price. It just needs a new caring owner who is an enthusiast.

Included with the sale will be all of the above plus:

- Clean title

  • - High quality car cover

  • - Battery tender for Winter storage

  • If desired, all of my W126 spares and this is extensive to include:

    • Interior door panels

    • Taillights

    • Antennas

    • Valve cover

    • Boxes of electrical switches, lights, relays, window switched, opera lights, etc.

    • Rear Parcel shelves

    • Rear interior side trim

    • Door cards

    • Sun visors

    • Filters, gaskets and new engine belts
