Jay Leno revealed a $10 million 'buried treasure' barn find, the rarest Mercedes Gullwing ever discovered

  • Jay Leno had the chance to have a closer look at a rare Mercedes
  • Loosely related to the iconic 300 SL, this one is more track-focused
  • Even in this condition, it’s worth eight figures

Jay Leno uncovered a 1956 Mercedes-Benz Alloy Gullwing, one of the rarest Mercedes models ever made.

One of only 29 produced, it’s a rare iteration of a car that’s already rare to begin with.

It was kept hidden away in a Los Angeles storage garage for nearly 60 years.

And yet it feels like this beauty is only a car wash trip away from becoming showroom-worthy again.

The Alloy Gullwing is a track-inspired, all-aluminum iteration of the Gullwing Mercedes.

The engine is a 3.0-liter, 215HP NSL engine, but of course, the main point of the model is the body shape with the gullwing doors.

It’s such an iconic car.

As Jay Leno pointed out in the video on his YouTube channel, this was the world’s first fuel-injection car, a type of technology that, at the time, was reserved for fighter jets.

Also, again according to Leno, this, not the Lamborghini Miura, is the world’s first supercar.

Which could explain why this car is worth around $10 million. And while that’s not cheap, it’s still relatively ‘average’, believe it or not, for these cars.

A while back, a 1956 Mercedes-Benz 300 SLR, which in a way is distantly related to the very car you see here, sold for a staggering $142 million.

To be fair, that vehicle was sold under unique circumstances.

It was a private auction organized by Mercedes themselves, and it was for a vehicle that had been sitting in a Mercedes museum for ages until then.

Even so, nine figures for a car is truly outrageous.

Alternatively, there are cheaper, or perhaps we should say, less expensive, variants which sometimes go for ‘just’ seven figures.

A heavily modified Mercedes 300 SL recently went for $1.6 million.

But then again this is one of those vehicles where the year, or a different letter in the name – any detail, as minute as it might look – can make a difference and affect the value.

This one in particular, even in this condition, is worth at least $10 million.
