I'll do my best to answer all questions in order:
Couple of questions...
You say no harness or throttle body issues, but are they original or have the both been replaced?
And evidence of the MAF sensor being replaced?
What all was done when you had the head off?
Have the SLS spheres been replaced?
See above re: harness & throttle actuator.
Haven't checked the MAF for a date code, but no reason to suspect its failing.
Before removing the cylinder head I recorded excellent compression & leakdown #s across the board (to make sure it was a project worth undertaking!) Upon removal of the head, found an imprint on the compression ring @ cylinder #2 from a piece of unknown garbage which was trapped there and must've slowly eroded over time finally allowing a small leak between the cooling jacket & #2 combustion chamber. The gasket was NOT a MB part & my assumption is that someone did a cheap head gasket a few years before I took ownership. I took the cylinder head to a trusted local machine shop that our dealership uses regularly for BMW & Porsche head work. The head was dipped, cleaned & checked. I was assured that it was in excellent shape with no warping or other issues & that even the valve stem seals were still in good order. I went ahead & had them replace the valve stem seals regardless with new Mercedes/dealer parts (provided by me!), do a valve job & a very thin cut to give me a fresh sealing surface on the head. Used a Mercedes/dealer head gasket & replaced a TON of other related seals while the cylinder head & manifolds were off. To be clear, I have & will provide to the next owner $3300 worth of receipts from the last 6mos (the time I've owned the car).
These are not marked up parts, that's $3300 MY COST on everything with a total price of $0 applied to my own labor. Were I to mark up the parts to retail & then apply my book rate to the job, it would very quickly price the car WAY out what any reasonable person would be willing to pay. I was planning all along to keep this car as a daily driver, but my family is better served by the W210 I'm now in.
The nitrogen accumulators can't be TOO old as the car exhibits none of the awful pogo-ing in the rear that results from their aging/failure. Both rear hydraulic shocks are dry & the system functions perfectly when loaded (just ask my 175lb English Mastiff).
Why is the coolant reservoir all brown in color? That doesn't look good... maybe post a photo showing the liquid inside with the cap off?
Otherwise the car looks nice. Rare color!!
The car came to me with the cooling system full of 100% H20 and its very possible the color you're noticing is the result of this. I have an unopened bottle of MB coolant + a bottle of MB citric acid flush. This is one of a list of things I have not had time to finish & which will be passed on to the next owner. Other things on this list include unopened MB transmission fluid, filter & gasket, a left tie rod & several other little things I don't remember off the top of my head.
Nit-picking the seller on a 200k mile $4k car guys? Come on.
To the OP, love the color combo. Obviously a well cared for 124. GLWS!
Thanks for that, well put. I'll leave it at that. . .
Actually, it's a $3k car in the Tampa Bay market. The worst thing is the color, believe it or not. After that the mileage is an issue because it's a vergasser. A diesel wouldn't be an issue, but a lot of people are afraid of the M103/104 with this kind of mileage, even with the work that's been done.
A very nice car, for sure, and well presented. I would post it to the local Craigslist and see what it will bring. You could probably get $3500 for it there.
Couldn't disagree more, but that's okay. If I'd seen a W124/M104 wagon this nice in Tampa Bay for $3k at any point in the last 5+ years, I'd have bought it myself. In fact, I paid $2300 for this one w/ a bad head gasket knowing full well what it would cost me to repair. . . Its VERY easy to score a W124 with a LONG laundry list of expensive repairs required to even drive it daily, not so for a car that is ready to go as-is with a short list of known issues that can easily be tackled by the next owner. And personally, I think the color/paint is one of the best things going for it!!!
In the end, I'm sure any serious buyer will contact me directly with any questions they may have & set up a time when they can see the car in person & drive it.
The proof is in the pudding!!!
