You’ve probably seen the old Top Gear episode where they put a Hilux on top of a building and blew it up. It still started. That wasn't just TV magic; it's the reason why, nearly fifty years later, people are still scouring the internet looking for a 1978 Toyota Hilux for sale.
It’s a weird market right now.
Back in the late seventies, these were just tools. They were the trucks farmers used until the floorboards rusted out or the odometer spun around for the third time. Nobody thought they were "classics." They were just reliable. But today, finding a clean third-generation (N30) Hilux is like hunting for a needle in a haystack—if the needle was made of Japanese steel and could survive a nuclear winter.
The 20R Engine: Why people pay a premium
If you're looking at a 1978 Toyota Hilux for sale, the first thing you check isn't the paint. It’s the engine code. The 1978 model sits in a sweet spot because it features the 2.2-liter 20R overhead-cam four-cylinder.
It’s legendary.
Engineers like to talk about "over-built" machinery, and the 20R is the poster child for that concept. It produces about 90-95 horsepower, which sounds pathetic by modern standards, but the torque curve is flat and the reliability is unmatched. It uses a timing chain rather than a belt, meaning you don't have that nagging fear of an interference engine blowing itself apart at 70 mph. Well, if you can even get it to 70 mph. These aren't highway cruisers. They are geared for work.
Most owners will tell you the 20R is basically a tractor engine in a pickup body. If it has oil and water, it'll probably run. I’ve seen these things sitting in fields for a decade, only to fire up with a fresh battery and some starter fluid. That kind of mechanical soul is exactly why the prices are creeping up toward $15,000 or even $25,000 for "survivor" units.

The "Round Eye" Aesthetic and the 1978 Transition
The 1978 model year is actually quite significant for collectors. It was the final year of the third generation's initial styling before the 1979 redesign changed the body lines significantly.
You get the round headlights.
Those "round eyes" give the truck a vintage, friendly look that the later square-headlight models just don't have. It feels like a piece of history. Inside, it’s sparse. You get a vinyl bench seat, a thin plastic steering wheel, and maybe—if the original buyer was feeling fancy—an AM radio. There are no airbags. No ABS. No power steering in most cases. You feel every pebble in the road through the steering column. It’s visceral. It’s loud. It’s honestly a bit exhausting to drive for more than an hour, but you’ll have a smile on your face the whole time.
Where to actually find a 1978 Toyota Hilux for sale
You aren't going to find these at your local used car lot next to a 2018 Camry. The market has shifted to enthusiast auctions and niche Facebook groups.
- Bring a Trailer (BaT): This is where the "museum grade" trucks go. If you find a 1978 Hilux here, expect to pay a "curated" tax. Prices here often defy logic because of the bidding wars.
- Facebook Marketplace (The Wild West): You’ll find the best deals here, but also the most rust. Search for "Toyota Pickup" rather than "Hilux," as Toyota didn't officially use the Hilux name in the North American market during this era; it was simply called the "Toyota Truck."
- Japanese Auction Houses: Some importers are bringing "Low-Lux" (lowered) or original 2WD models over from Japan. These are Right-Hand Drive (RHD), which adds a cool factor but makes drive-thrus a nightmare.
Rust is the killer. Specifically, the bed seams and the frame near the rear leaf spring hangers. Toyota used relatively thin steel for the beds back then, and since these were work trucks, they often hauled damp hay, salt, or dirt that sat in the corners for decades. If you see "diamond plate" patches on the floor, walk away. Or, at least, bring a magnet and a flashlight.
The reality of daily driving a 50-year-old Toyota
Let's be real for a second. Owning a 1978 Hilux isn't all sunset drives and thumbs-up from strangers.

It's a hobby.
You will be dealing with 1970s electrical systems. The "fusible links" can be a headache if they've been hacked up by previous owners. Parts availability is surprisingly good for mechanical bits—you can still get 20R gaskets and water pumps at most local auto parts stores—but body trim? Forget it. If you crack a grille or lose a specific piece of chrome molding, you'll be spending months scouring eBay or specialized forums like ToyotaMinis or YotaTech.
Identifying a genuine "Survivor"
When you find a 1978 Toyota Hilux for sale, check the VIN. The chassis code should start with RN28 (for the long bed) or similar variants.
Look for the original California emissions equipment if you’re in a state that requires it, though most of these are now smog-exempt depending on your local laws. Original paint colors were fantastic—paints like "Yellow" (Code 541) or "Copper" are highly sought after. If the truck has been repainted, ask why. Was it a color change or a cover-up for Bondo? Use a paint depth gauge if you're dropping serious cash.
A genuine survivor will have "patina," but there’s a difference between cool surface wear and structural rot. Tap the frame with a small hammer. A solid "tink" is good. A dull "thud" means you're looking at a pile of iron oxide held together by hope.
Why the investment makes sense now
Values for Japanese classics (the "JDM" boom) have already spiked for cars like the Supra and the Land Cruiser. The Hilux is the next logical step. It represents a specific era of Toyota’s dominance in build quality.

People want simplicity.
In a world of touchscreen dashboards and subscription-based heated seats, a truck that requires a manual choke and a physical key is an antidote. It’s an analog machine. Even if you don't plan on off-roading it, just knowing it could cross a desert makes it feel special.
Essential Pre-Purchase Checklist
- Compression Test: The 20R should show around 150-170 PSI across all cylinders.
- Steering Play: These manual boxes get sloppy; check the tie rods and the steering dampener.
- The "California Bed": Check if it’s a "smoothie" bed or the one with the external tie-down hooks. The external hooks are more common on early imports and have a distinct vintage look.
- Wiring Harness: Look for "vampire clips" or electrical tape. Mid-70s Toyotas hate bad grounds.
Taking the next steps
If you are serious about buying, start by setting up saved searches on specialized sites like AutoTempest or Bring a Trailer. Don't jump on the first one you see unless the frame is pristine. It is much cheaper to buy a truck with a blown engine and a perfect body than a running truck with a rotted frame.
Join the "70s-80s Toyota Pickup" groups on social media. Often, the best trucks are sold "within the family" before they ever hit a public listing. If you find a 1978 Toyota Hilux for sale that fits your budget, move fast. The secret is out, and these "indestructible" legends are finally being collected by people who actually know what they’re worth.
Check the frame, verify the 20R health, and get ready for a lot of conversations at gas stations. Everyone has a story about a Toyota truck they shouldn't have sold. Don't be that person.
