Hey Guys,

This is my first post on here but I've learned some awesome tricks on like the holes in the Thermostat and other little tricks so thank you!

Now, I finally almost done with my car that I basically rescued from the dead and brought it back to life.

I have been going back and forth on what the value would be as I am most likely selling it here shortly. I just don't have a garage for it anymore, which sucks! :(

It's only got 106k miles, verified. The interior is absolutely immaculate, I love the blue on it - the exterior paint was freshened up. Some apparently rich guy from Palm Springs owned it and then donated it to charity, I purchased it from a friend knowing I'd have to do some items to it (listed below).

I had king of gathered some data that is telling me between 16k-20k, but I could be wrong???

What I did:

4/18/2025 - Behr Radiator Installed (newer style).
4/18/20205 – Thermostat + Coolant flush done
4/19/2025 – Diesel Purge completed w/ Diesel Kleen, Rislone Hypercool added to coolant.

5/6/2025 – Valves Fully Adjusted (Intake / Exhaust) done by Sam Golden (Mercedez Geek).
5/10/2025 – Installed new thermostat (Murray 180 degree) and did Benzworld (better flow) procedure.
5/23/2025 – Tires Mounted and rebalanced, check with Tire shop and okay (no checking, or cracking). Done at 105,860 miles.
5/24/2025 – Ordered newer style and updated Alternator from Amazon + H4’s.

6/01/2025 – Had Sam (check over mileage tracking on Odometer), cleaned up internals and lubricated gears. (Not adjusted or rolled) $150.00
6/6/2025 – Removed old SERVO II Climate Controlled unit (old style plastic body) cracked – rendering bad unit. Ordered new SERVO II Unit off eBay for $600.00 and check Amplifier and checks good. New Body style Servo Unit from Christian with Aluminum body’s and rebuilt (MBDIESEL1).
6/10/2025 – Swapped Batteries on car, old one having issue with holding charge.
6/25/2025 – Complete fluids done at 106,130 w/ AC DELCO 15w40 Synthetic DIESEL type of oil + added in Benz recommended Mos2 anti-friction Liqui Moly.

Hi Carlos. It looks absolutely gorgeous.

Can I recommend putting the car into your profile or garage?

Thank you, a lot of love went into her! I will take some more pictures of the engine bay. The AC Compressor has been updated and changed and updated to R134a, I need to vacuum it down and then pump some new freon in it, I think it may have air in the system. I did a spot small charge of it, and the compressor started engaging. New Servo as mentioned, and I do get heat now... lol these old systems are funny but still work!
