Technical data: W116 E28 chassis
2.8 Litre DOHC Inline 6 cylinder gas engine
182 hp @ 6000 RPM
Bosch K-Jetronic (mechanical) fuel injection
3670 lb unloaded weight.
The Euro spec W116 is faster and lighter than its American counterpart, it has 40 more horsepower and about a hundred pounds less weight. American regulations required large "park bench" bumpers, which, thankfully, were not required on grey market imports. The paint color is called "Milan Brown Metallic" I think, at least that is the closest color I can find in MB's color charts. It's not bad, but I prefer this car in lighter metallic color, as in the 450SEL 6.9's silver metallic with chrome door panels and wheel arches.
The doors, rocker panels, and most exterior surfaces are clean and very straight. The doors open and close without any rubbing or signs of a bent frame. This is normal for an S-class tank that hasn't been in any accidents. Unit-body construction this heavy won't tend to sag or pinch the doors, but an accident could be told in doors that rub.
The engine cranks, runs and sounds good. We didn't have enough carburetor cleaner to run it for long, fortunately. I expect we will be going through the engine a bit, although there's not much there that needs doing. Valve timing is provided by duplex chain and dual over head cams, so I expect these to be in good order. A good steam clean and compression check with a tune up will turn up any unexpected top end issues.
A typical problem with Bosch mechanical fuel injection is condensation on the top of the gas tank, as witnessed by our VW Vanagon from the 1980s which very nearly blew Dad up one day.
The owner of this Mercedes said his mechanic told him there was a leak in the gas tank, and not to drive it. Typically what will happen is the gas evaporates through a small hole into the trunk, which will smell strongly of gasoline and perhaps explode if you should open it whilst smoking a pipe. I didn't find any gas smells in the trunk (or a spare tire), but I did find that the gas cap had been run over and completely deformed at some point. This may or may not be the cause of their leak. Pressure testing the gas tank with a new lid might be in order. If that fails, the tank will need to be pulled out, welded or replaced.
I can't remember driving any Mercedes with a plush/velour interior. I know they exist, but if you're paying that much for a car, why not make it at least Pleather, if not the real stuff. Either way, UV rays have not been kind to the velour, and the inside of this car looks like a Star Trek uniform left to the weather. It has to go to the upholstery shop for a tear down and re-hide.
The only thing you can do about rotting wheel wells is make them entirely out of plastic. I don't know why this isn't done, but it isn't. The wheel wells show the usual rust and will require work and a complete repaint. This is not some cheap Maaco job for $300 either. Getting the real paint from MB, having a professional spray it after perfect preparation is the only way to go. Whether or not we will go that way is to be decided later..
There are many options for this kind of thing. You could go all-black AMG for example. With this look, you have to wear all black (Members Only of course) all the time. And a German stainless steel watch, not Swiss.
OR, you could go all negative on the colors with black on white, more of a tuning car apparel. In this case you would have to wear a white track suit with black piping ALL the time. You will also need a large digital chronograph on a lanyard.
