Jay Leno’s garage houses 'Holy Grail' of limited cars you won't see anywhere else on Earth

Within Jay Leno’s garage is a ‘Holy Grail’ of limited cars that you won’t find in any other garage on this planet.

The former host of The Tonight Show is a big car aficionado; there’s no disputing that.

But even for a car lover of his stature, these cars are impressive finds.

These ten vehicles are rare sightings on our roads, and Jay Leno has them in his possession.

The limited cars that fill up Jay Leno’s garage

Jay Leno owns more than 180 cars, and they all get their fair share of time on the road.

There’s a reason his collection is the third most popular with Google searchers, trailing only Cristiano Ronaldo and Bill Gates.

His collection is estimated to be around $100 million, and that figure alone is staggering.

These cars span the decades and manufacturers, but some are rarer than others.

We’ve compiled a list of ten cars in his collection that are extremely rare – some are one of a kind.

1) 1934 Duesenberg Walker Coupe

Estimated to cost approximately $20 million, the 1934 Duesenberg Walker Coupe is likely the most expensive car sitting in Leno’s garage.

This was built for Josiah Lilly, the president of pharmaceutical company, Eli Lilly.

At the time, it was the most expensive Duesenberg ever built – but Lilly wasn’t a fan, as it was too cramped and drew too much attention during the Great Depression.

Leno ended up buying it from a wealthy owner for half a million – a huge increase on the $400 that the owner had spent acquiring it.

2) EcoJet Turbine Car – an entry in Jay Leno’s garage designed by Jay himself

This car was born out of a collaboration between Leno, General Motors, and Honeywell.

At the heart of this creation is a Honeywell LT-101 turbine engine, typically found within Bell 222 helicopters.

As the name suggests, this car is built with the environment in mind, so it runs off biodiesel (soybean oil, in fact).

The EcoJet has two fuel tanks – one with standard jet fuel to start the engine, and the other with biodiesel to run it once it gets hot.

It got its big debut at the 2006 Specialty Equipment Market Association (SEMA) show.

3) Blastolene Special (Tank Car)

The engine of this car is a 29-liter V12 from a M47 Patton tank, originally capable of producing 810hp.

Leno sent it over to Gale Banks Engineering to be twin-turbocharged, and now it produces 1,600hp.

Despite the car clocking in at 9,500Ibs, it’s surprisingly quick on its wheels.

You may recall that this vehicle featured in the Gran Turismo video game series.

But don’t think this car is just for the digital streets – it’s street-legal in real life too.

It wouldn’t be the first time a Gran Turismo car would see usage in the real world, as Supercar Blondie found out for herself.

4) 1966 Oldsmobile Toronado

At first glance, this car wouldn’t look too out of the ordinary.

But this is actually a C5 Corvette inside a 1966 Oldsmobile body – Leno’s team at Big Dog Garage had to lengthen the chassis by 14 inches to fit the body.

A twin-turbocharged V8 sits at the heart of this car, producing over 1,000hp.

5) 1906 Stanley Steamer Racer

Back when this car came out in 1906, it could reach speeds of 75mph, which was extremely fast for the time.

It’s practically silent, which runs contrary to our ideas of old cars being wheezing buckets.

Operating it is no piece of cake though, as Leno himself found out in 2022 when a fuel line sprayed gas on his face and ignited while he was working on it.

6) 2006 Pratt and Miller C6 RS

This car was built as the ultimate road-going Corvette, with an 8.2-liter V8 at the heart of it.

This is larger than any other engine GM has put into a production Corvette.

Seven were built, but this was Leno’s was the first of the bunch – the one that got shown off at SEMA.

7) 1963 Chrysler Turbine Car

55 of these were built originally as an experiment, before all but nine were crushed.

Leno bought his directly from Chrysler in 2009.

This turbine engine can run on almost anything that is flammable, whether diesel or kerosene.

And yes, that does include alcohol – unsubstantiated rumors have it that a President of Mexico once ran one of these cars on tequila.

8) MTT Y2K Turbine Superbike

This motorcycle was once branded the ‘Most Powerful Production Motorcycle’ by Guinness World Records.

It’s no wonder, given how it’s powered by a Rolls-Royce Allison 250-C18 turboshaft engine.

If you want a gauge of how powerful this bike is, hear it from Leno himself.

“It’s frightening to drive, but it’s exciting to drive,” he said.

When you hear it kick into power, you’d swear you were inside a plane that was about to take off.

9) Mercedes 300 SL

At first glance, this car isn’t that rare – 1,400 Mercedes 300 SL with Gullwing doors were made, after all.

However, this is one of 29 aluminum versions meant for racing.

Their rarity makes them worth millions more than their steel counterparts.

10) The final limited car in Jay Leno’s garage – 1963 Jaguar XKE V12

This car is something of a mystery, as the V12 E-Type didn’t launch until 1971.

That makes this car an odd one, given it came eight years earlier – was it a prototype or an experiment?

At any rate, it’s distinctive and belongs to Leno.
