1998 Mercedes C43 AMG Ute — Bad Ideas Garage

The $1,200 AMG

Dale convinced me I needed an inexpensive AMG. This is a sentence that has never led anywhere good, and yet here we are. The 1998 C43 AMG showed up on Facebook Marketplace for $1,200, which for a hand-built 4.3-liter V8 sedan that was the fastest production sedan in the world in 1998 is, objectively, a ridiculous deal. It was dirty, had been sitting, and needed a battery. It also had a lot of deferred maintenance from a previous owner who had taken a creative approach to car care. But it ran. And once it ran properly, it ran well.

The original owner had it until somewhere around 222,000 miles, according to the Carfax. By the time it got to me it had 253,000 on it, a disconnected sway bar, and a list of deferred maintenance long enough to be its own video series — which it became. I learned a lot about German cars working through that list, mostly with Dale's help. And then I took it to Portland International Raceway for HPDE track days, because of course I did. At 253,000 miles. On a car I paid $1,200 for.

On Track

In 1998, the C43 AMG did 0–60 in just over five seconds and was the fastest production sedan on the market. It's not exactly that fast anymore, but the 45–125 mph pull on a track is still an absolute rocket ship. The V8 hit speeds around 125 mph at PIR and didn't complain once. Nearly 250,000 miles and still kicking.

The Accident

In 2020, while my wife was eight months pregnant, the C43 got sandwiched between two trucks on a backroad cruise. Everyone was fine — wife, baby, me, the dog. The Mercedes did exactly what a well-engineered car is supposed to do: it absorbed the impact and kept the people inside it safe. The rear passenger side took severe structural damage. Even after we tried to straighten it out, it's still a little crooked. But it held.

I was ready to scrap it. I'd put too much work into it to feel good about that, but the damage was serious and we were about to have our first kid. Dale and the crew had a different idea: cut the damaged section off, turn it into a Ute, and run it in the Gambler 500 as a send-off. A swan song for a car that had earned it.

The Conversion

Jamie did the heavy lifting on the original build — hand-fabricating a custom roll bar, fitting a rear window sourced from a junkyard Eurovan, and starting the bodywork. The roof came off, the damaged rear was cut away, and what was left was a 1998 Mercedes AMG pickup truck. We replaced the smashed radiator and water pump, attempted to pull the rear frame with a winch, and called it Gambler-ready.

The Gambler 500 run was everything. The Ute went through snowy mountain passes and tackled the Christmas Valley sand dunes on summer tires. It got stuck a few times. It also performed like a rally car through most of it. Track suspension, no four-wheel drive, a slightly crooked frame, and it just kept going. My spine has not fully recovered.

After the Gambler, the fabrication saga continued. A self-described metal specialist stripped the car to bare metal and removed the roll bar in pursuit of a steampunk vision that nobody asked for. Raleigh stepped in and rescued the bodywork, getting it smooth again. After a wrap by Xtreme Grafx, the Ute became what it is today: a functional, genuinely cool vehicle that goes to car shows, hauls lumber from the hardware store in its 5.5-foot bed, and is apparently a favorite play area for my son.

The Next Chapter

The original M113 V8 eventually started showing signs of its mileage: coolant consumption, a timing chain that had stretched enough to be visible moving through the oil filler cap, and oil that had started to look more like a latte than motor oil. For a lot of engines, that's the end. For the M113, it just means it's time for a swap.

The Swap

My friend Andrew — of The Auto Informant on YouTube — sourced a 1997 grey-market E55 AMG as a donor. The E55's 5.5-liter M113 V8 made approximately 350 horsepower from the factory, got a tune on top of that, and had significantly lower miles than the outgoing engine. Going from a high-mileage 302 hp engine with milky oil to a refreshed, tuned 5.5-liter is not a small upgrade. The swap is in progress and I haven't driven it yet. I expect it to be unreasonably fast for a truck.

Where It Stands Now

The E55 swap is being finished up by Andrew. Once it's done, this car goes from a $1,200 Facebook Marketplace AMG that survived an accident, a Gambler 500, two failed fabricators, and 250,000+ miles — to a tuned 5.5-liter V8 Ute that is one of exactly one in existence. It's been a wild journey and it's not over yet.

Build Highlights

The short version of a very long story.

The Donor E55 is Found

A grey-market 1997 E55 AMG gives its heart to the Ute. It hurts to part out something special — but it's for a good cause.

Step 1: Remove the Doors

The engine is coming out of the E55. First step? Remove the doors. Because they'll just get in the way.

Goodbye, E55

Saying goodbye to the W210 E55 parts car. One car ends so another can continue. The 5.5L M113 is headed for the Ute.
