1985 Mercedes 500SEC AMG 5.4 Widebody 540SEC


I know I’ve posted a lot of Mercedes lately, but that is my passion. Some I post I smile and say, “that is nice”, but some I find and I go “Hell Yes!!” This is one of the later.

Mid eighties Benz cars with genuine AMG modified engines are not very common. You’ll see a number of cars with body modifications, but usually that Miami Vice style look stops with the exterior. This one has the full treatment including one of AMG’s interior, suspension, and engine packages.

This is a low 15,000 mile grey market Euro vehicle. With such low miles it is not surprising that the car looks immaculate. The interior has a dual color treatment similar to some of the modern Designo models and includes a rare 300 km/h AMG speedo. Check out the selection of options on the power seats. Those are Recaro CSE seats that if sold by themselves can go for almost $2000 a piece.

The rear end has been flared out to fit thick meats on the rear wheels.
What really sets this apart though, as I mentioned above, is the engine. The engine bay houses a rare AMG 5.4 liter engine, note the AMG valve covers. This is a very scarce motor. It was third down in terms of power packages that AMG offered in the mid eighties. Number one was the 6.0 liter Hammer motor, which came a bit later, number two was a 5.0 liter 4 valve per cylinder engine that bumped out a conservative rated 340 horsepower and 457 Nm of torque. The 5.4 in this car is a pushed out version of the stock 5.0 liter M117 engine, it puts out 310 hp and a solid 475 Nm of torque.

The seller states that this is one of 25 cars with the 5.4 liter and the widebody conversion. Hard to say what the real number is, but that does not sound unreasonable.

With several days left to go the price has already reached over $25,000 with multiple bids, and the reserve not met. You can tell by that sort of price that this is not your typical 500SEC that you find in your local swap sheet. The rarity is clearly appreciated by aficionados. I would love to have this in my garage.

UPDATE: this eBay auction mysteriously disappeared, possibly a fraudulent seller. The auction did look legit, but if you see this car appear online again be careful. Like I mentioned above there are very few Benzs out there carrying this engine.
UPDATE 2: as you can see in the comments section below the seller contacted us to say he is legit and the auction was pulled due to the Euro VIN # problem we’ve seen other sellers run into when selling grey market cars on eBay.

    Bummer that it got pulled! I wonder if they found a buyer locally or someone made a huge offer they couldn’t refuse…

    hello there and thank you for the nice introduction on this AMG it is mine. just wanted to correct some of the comments on why the car was pulled out of the auction,
    This is a Euro AMG Model not US model ebay (USA) system dose not recognize the Euro cars vin because it is not in there data bass system so when i listed the car i used all zeroes for a vin, of course that was not accepted by Ebay and later on cancelled the auction, that is all no fraud car is genuine and original and is back on ebay now. mean while here is my web album above some i sold and some i still have thanks again.
