Rare 1928 Bentley Barn Find Could Be Worth Over $1 Million
Surviving Vanden Plas coachwork, low production numbers, and past Bentley 4.5 Litre auction sales all shape the car's potential seven-figure value.
Colin Smith was filming an abandoned UK property for his YouTube channel when he found something most car hunters only dream about: a 1928 Bentley 4.5 Litre Sports Tourer, its Vanden Plas coachwork still intact after years untouched.
The body style alone makes it rare. Bentley built around 720 examples of the 4.5 Litre between 1927 and 1931. Vanden Plas bodied just 204 of them, with only 148 finished as four-seat tourers like this one.
Why This Barn Find Is Rare

More than 50 of those cars left the factory in 1928 alone. That puts this particular Bentley squarely in the earliest and smallest production window for the model. The naturally aspirated 4.4-liter inline-four, fed by two carburetors, produced 110 horsepower in standard touring trim.
Surviving pre-war Bentleys rarely keep their original coachwork this intact. Barns tend to be unkind to wood-framed bodies and thin steel panels. A Vanden Plas tourer that still carries its factory body and has never been through a fire is already unusual before anyone even checks the chassis numbers.
A registration check reportedly traced the car's factory finish to black, though whether that paint is original or a later repaint still needs verification. That detail sits at the center of any future valuation. Matching-numbers cars with documented history command a different market than cars with gaps in the paper trail.
The Bearded Explorer offered a blunt read on where this one fits. "This barn find is the naturally aspirated flavor, which still means seven figures is realistic once it's authenticated and restored, just not Blower money," they said, drawing a line between this car and Bentley's supercharged variants.

Recent sales show just how far apart two outwardly similar Vanden Plas Bentleys can land. A 1928 example sold at Broad Arrow's Villa d'Este sale in May 2026 in roughly the mid $400,000 range, based on publicly available valuation summaries.
Chassis RL3427 carried matching numbers and unbroken ownership history into RM Sotheby's Monterey sale in 2021, where it brought $1,105,000. Another original-bodied Vanden Plas Semi-Le Mans Tourer sold for $2,750,000 at Gooding & Company's Amelia Island auction in 2013, riding its racing pedigree and factory-correct coachwork to that result.
That spread runs from under half a million to nearly three million dollars for cars sharing a chassis and an engine.
Authentication decides everything here. Buyers at this level pay for paperwork as much as sheet metal, and a barn find with no sale history starts well behind a car with a documented chain of ownership.
Whether Smith's discovery lands closer to those mid-$400,000 results or climbs toward seven figures depends on work nobody has done yet: confirming matching numbers, tracing the ownership record, and assessing how much of the original coachwork survives beneath years of neglect.
Collectors watching this story, the kind who also track results on cars like the rare Ferrari 250 GT or recent record-setting Bugatti sale, know that provenance research often takes longer than the restoration itself.
