The vintage Bentleys: 3 Litre to Blower, the cars of the Bentley Boys (1921–1931)

The Cricklewood Bentleys won Le Mans five times in eight years, gave the world the Blower and the Speed Six, and bankrupted their maker building the 8 Litre masterpiece. A guide to the W.O. era, the Bentley Boys legend, buying realities of the marque's grandest era.

What they sell for at auction
The models

For one decade a factory in Cricklewood built the fastest lorries in Europe, Ettore Bugatti’s jibe, and the fact that everyone repeats it fondly tells you who won the argument. W.O. Bentley’s 3 Litre, 4½ Litre, Speed Six and 8 Litre won Le Mans five times in eight years, gave the twenties its most glamorous heroes, and created in the Blower Bentley the most famous Bentley of all. The vintage cars now trade at the summit of the British market, and their world has never stopped racing.

Five wins in eight years

The 3 Litre established everything: fast, strong and unburstable per W.O.’s creed, it won Le Mans in 1924 and again in 1927 through the White House crash epic, Davis and Benjafield nursing the battered Old No. 7 home past newer, faster rivals in the race’s first great legend. The 4½ Litre took 1928 in Barnato’s hands, and the Speed Six, W.O.’s big six at full development, delivered the imperial phase: 1929 and 1930, Barnato aboard for both, three consecutive wins for the diamond heir who also bankrolled the company. Five wins in eight years fixed British racing green in the world’s imagination and made the winged B eternal.

Birkin, Paget and the Blower gamble

The Blower was heresy that became scripture: Tim Birkin, fastest and most romantic of the Bentley Boys, believed supercharging the 4½ would beat the Speed Six, and with the Hon. Dorothy Paget’s money built the 55-car run over W.O.’s objections, the Amherst Villiers blower worn ahead of the radiator like a challenge. It never won Le Mans; it led it heroically, broke records at Brooklands, and seized the legend anyway. Ian Fleming later put Bond in one, and originals now trade in the millions, with the modern factory’s continuation run only confirming the aura.

Barnato, the Blue Train and the style

The Bentley Boys made the cars half the story: Barnato’s 1930 wager that his Speed Six could beat the Blue Train express from Cannes to his London club, won with time to spare, remains motoring’s best anecdote, and the set’s Mayfair flats, Brooklands weekends and Le Mans triumphs defined an era’s glamour that the marque has traded on ever since. Kidston flew, Benjafield doctored, Davis wrote, and all of them raced with a style the sport has never quite recovered. Behind the style stood W.O.’s final masterpiece, the 8 Litre of 1930, one hundred colossal chassis that out-Roycd Rolls-Royce and helped bankrupt the company into the receiver’s hands by 1931, when Rolls-Royce bought its rival and the Cricklewood decade closed.

What a vintage Bentley is like to drive

Everything is big: the wheel, the gearing, the outside handbrake, the four-cylinder cars’ thunder and the sixes’ effortless surge, managed through a crash box that rewards learned technique and a chassis that steers heavy, true and alive. First acquaintance is physical work; fluency arrives within a weekend and turns the effort into the appeal. Speed builds with intent rather than ease, and a 4½ at pace on a modern road remains a genuine event for every sense. The vintage Bentley world drives hard, Benjafields club races, continental tours, Peking to Paris included, and a car with sporting patina stands taller in it than any static restoration.

Specials, rebodies and continuations

A century of hard use built the market’s most layered hierarchy: most surviving tourers wear later or replica-pattern open bodies, honestly priced below original coachwork, while chassis rebuilt into sporting specials over the decades occupy their own well-understood tier, valued on the quality of the work and the completeness of the original car beneath. Above them sit the untouched originals and the period team cars; alongside them, the modern factory’s continuation Blowers and Speed Sixes, built to period drawings at seven-figure prices, which have confirmed rather than diluted the originals’ standing. None of this is deception, because the registers document every car’s construction history line by line; it is simply a market where the same badge can price across two orders of magnitude, and where knowing exactly which layer a car occupies is the whole game.

Buying into the W.O. era

This is registry country: chassis, engine and body histories are documented car by car and argued over in print, rebodies (most survivors wear later or replica Vanden Plas-style tourers) are priced distinctly from original coachwork, and period competition history multiplies everything, Team Car provenance most of all, with Le Mans miles the market’s rarest currency. Specials and continuation cars occupy honest separate tiers. The specialist houses and the Bentley Drivers Club hold the knowledge, and no purchase at these values should move without them. At 218 measured sales and a £345,000 median, 3 Litres from £180,000 to Blowers in the millions, the vintage market is the British hobby’s summit, and it prices scholarship accordingly.

On money, the Cricklewood cars are priced almost entirely by engine size, from a 3 Litre tourer to the 8 Litre, and more of them fail to find a buyer than any other car on this site. The full record, 218 recorded sales, is on the page covering what a vintage Bentley sells for.

Quick answers

Frequently asked questions

What is a Blower Bentley?

The supercharged 4½ Litre of 1929–30: Sir Henry Tim Birkin, backed by the Hon. Dorothy Paget, persuaded the company to build 55 cars with an Amherst Villiers supercharger mounted ahead of the radiator, against W.O. Bentley's own engineering judgement. The Blower never won Le Mans, but its speed, drama and Birkin's heroics made it the most famous Bentley of all, and originals now trade in the millions.

Who were the Bentley Boys?

The gentleman racers who made Cricklewood immortal: diamond heir Woolf Barnato, aviator Glen Kidston, journalist S.C.H. Sammy Davis, Dr Dudley Benjafield and Tim Birkin among them, wealthy amateurs who raced the big green cars to five Le Mans wins and lived with matching glamour. Barnato's Blue Train race, beating the express from Cannes to Calais in his Speed Six, remains the era's defining anecdote.

Why did Bentley go bankrupt in 1931?

Racing glory never paid: the company lived hand-to-mouth throughout the twenties, Barnato's fortune underwriting it after 1926, and the Depression finished the job just as the towering, expensive 8 Litre reached its few customers. Rolls-Royce bought the remains through a front company, ending Cricklewood production; the W.O. era lasted barely a decade and created a legend out of all proportion to its 3,000-odd cars.

Which vintage Bentley won Le Mans?

Four models share the five wins: the 3 Litre took 1924 and 1927 (the latter after the famous White House crash), the 4½ Litre won 1928, and the Speed Six took 1929 and 1930, the marque's imperial phase with Barnato aboard for three consecutive victories. The Blower, fastest of all in a straight line, never finished first, which has never dented its fame.

How much does a Vintage Bentley sell for?

Across 218 recorded auction sales, the median Vintage Bentley made £345,100, with most selling between £212,295 and £575,661 (as of August 2026). Those are sold prices rather than valuations: condition, history and specification move any individual car well outside that range.

What is the most expensive Vintage Bentley ever sold at auction?

The highest recorded auction result for a Vintage Bentley is £3,874,106, paid for a 4.5 Litre Le Mans in August 2012. Results like that are exceptional cars at exceptional moments; the typical range is £212,295 to £575,661.

How often does a Vintage Bentley come up for sale?

Frequently, by classic-car standards: roughly 13 sell at auction each year, and 64% of the cars offered find a buyer. There is a steady supply, so it pays to wait for a good one rather than stretch for the first car you see.
