Heaps of the Week: Two Mercedes 500SEC AMGs One seller

1985 Mercedes Koenig widebody project

Need something to keep you busy in the continuing grey days of winter? How about a pair of 500SECs projects to keep you out of trouble? (Well actually this may get you into trouble, financially or with your significant other) Carter also noticed this ride and linked it off our Facebook page.

Here we have what appears to be yet another case of picking up the pieces where a previous enthusiast ran out of time, money, or interest, but the seller instead states that they are selling due to illness. This may mean that the projects aren’t as bad as the ones being sold because someone got in over their head. Eitherway though that picture above shows a once great car looking sad. Not horrible though, we’ve seen a lot worse, but look at it just sitting there in a pile of leaves all cold and alone.

What we actually have is a rare, but non-running rare Koenig widebody 500SEC and a not as rare, but running parts car.

Here is what I take out of that description. I like that the Koenig hasn’t been traded around a lot, but has been with this one owner for 15 years. We see trouble cars get flipped over and over on eBay when a buyer realizes the car is not nearly as nice as the previous owner stated. This one hasn’t been flipped around a bunch, which I see as a plus. Looking at the photos though this car is, as the seller says, a diamond in the rough. It looks like it has been sitting awhile outside, sad. The tires are flat and the paint is cloudy.

The Koenig isn’t running because the owner states the car needs a distributor and fuel pump. I raise an eye at this a little. That is a fairly easy fix, especially with a second car where you can swap parts even just to test and make sure that is the problem. I understand if the seller is sick that they might just not be able to deal with this, but I think I would’ve tried to get that sorted before listing the car. It could be that there are bigger issues lurking. Eitherway a couple hundred to pay someone to do the swap off the parts car to show that this fixes the problem would’ve increased the sale price on the car.

It is also unclear what the seller means when he says the car was “custom made for racing.” I think in this case it is just the seller indicating the car was setup with extra horsepower increasing modifications and not hat it was actually tracked or drag raced, I hope not anyway as that really isn’t the W126’s forte. Normally however seeing text like that in add for a street car is reason to be weary. The seller menti0ons that the car has the brackets for a supercharger and that it did at one point have one attached. The pictures show a modified intake, which if it isn’t attached to anything may actually be impeding air flow. These bolt on supercharger kits can cause lean issues and premature engine wear, but the 5.0 liter is pretty robust and with under 100,000 miles should have some life left. The pictures make it look like maybe the car has been sitting a bit, the paint looks a little crazed and rough, but it is hard to tell.

The “parts car” (which looks like it is an easier fix than the non-parts car):

As the seller states, the parts car looks a little too nice to be separating. An eBay purchase by the seller, no doubt on the cheap, it looks like it was loved with someone investing $ to rebuild the top half of the engine in 2012. Not a stance guy, but there is too much space between the tire and the fender up front. Tucking that down or filling out the wheel wells a bit really helps the look of these cars.

I’m sure the seller is hoping for the top dollar that a nice Koenig widebody will bring in good shape. Unfortunately the presentation is just not here on this one. $25k as is would be surprising on eBay, last time it was up it ended at under $16,000. A little work, better pictures, and a cleaner presentation and I bet this would bring close to $10k more as these are rare cars with quite a following. It’s all in the marketing. Note to sellers, put air in your car’s tires before selling.

    What a shame. I would love to have the Koenig, but it’s not worth more than a couple grand. The bodywork alone would take at least $20k to get up to par, then there’s the interior and the entire drivetrain… Truly saddening. Even more so because of the seller doesn’t seem to realize just how trashed both his cars are?
