1959 Cadillac Eldorado Biarritz = $324k

In the late 1950s, Cadillac was the undisputed heavyweight champ in the full-sized luxury car market in North America. Cadillac used the nameplates "Eldorado Seville" and "Eldorado Biarritz" to distinguish between the hardtop and convertible. This top of the line car is one of 1,320 produced in 1959. The 1959 Cadillac is remembered for the largest tailfins ever and dual bullet tail lights.

While the 1959 Eldorado was misunderstood in its day, collectors today recognize the car's combination of power, presence, and unbridled extravagance. The Eldorado featured the ultimate engine of the late 50s, the Q-code 390-cu.in. V-8, topped by three two-barrel Rochester carburetors producing 345 hp.

This concours quality example made $324k in late 2018.

Steve McQueen's 1968 Ford Mustang GT 'Bullitt' - $3.7m

A beat up, dull green 1968 Ford Mustang GT driven by Steve McQueen in the movie "Bullitt" became the most valuable Ford Mustang ever sold at auction. It went for $3.7m in Kissimmee, Florida in 2020. The vendor was Sean Kiernan, whose late father Robert Kiernan purchased the car for $3,500 in 1974. McQueen tried to buy the car several times with no success. The 10 minute 'Bullitt' chase scene is considered the first and still one of the best 'modern' auto chase scenes. It set the standard for Hollywood car chases for generations.

1970 Dodge Hemi Challenger R/T - $302k

Original broadcast sheet. Nut and bolt rotisserie restoration. The only documented Plum Crazy Hemi 4-speed Challenger R/T with Shaker hood and Super Track Pack. 1 of 5 Hemi Shaker Challenger R/T 4-speed Hardtops known to exist. 426/425 HP Hemi V-8 engine. 4-speed transmission. Hurst Pistol Grip shifter. Plum Crazy with Black vinyl top and interior.

The Challenger could be had with 11 possible engines from a 6-cylinder on up, to versions like this, completely optioned for performance. Over the following four years, the car’s potential options list grew much smaller, leaving big-block examples from 1970 and 1971 as the apex collector models.

This example is exclusive as one of only five Hemi “Shaker” Challenger R/T 4-speed hardtops known to exist. The option was “delisted” in late 1969, and very few cars came with it again until the end of the production run. This Hemi features dual 4-barrel carbs, hydraulic cam and electronic ignition. The engine choice also brought specific suspension and frame components.

This top tier example made $302k at Kissimmee in 2020 against an estimate of $285k to $350k

1968 Dodge Hemi Charger R/T - $181k

17,000 Charger R/Ts were produced in 1968, but only 476 of them were armed with the 426 Hemi. 1 of 264 Hemi Charger R/Ts produced in 1968 with TorqueFlite transmission. Original sheet metal. 426/425 HP Hemi V-8 engine. TorqueFlite 3-speed automatic transmission. 3.23 ratio Sure Grip rear end. Matador Red with a White vinyl top and bumblebee stripe. White and Red interior with vinyl bucket seats. Power brakes. Hideaway headlights. Hood-mounted turn signals. Music Master AM radio.

For $3,506, the R/T came with the 375-bhp 440-cid four-barrel Magnum V-8, heavy-duty brakes, R/T handling package, and F70Xl4 tires. Some 476 serious muscle car fans ordered theirs with the monster 426 Hemi, a very serious $605 option. For that money one got an elephant engine severely underrated at 425 bhp.

Producers of the hit film Bullitt knew what they were doing when they cast the redesigned 1968 Dodge Hemi Charger R/T as Steve McQueen's foil. The 1968 Dodge Charger R/T Hemi was a muscle car with star quality. Charger's new hidden-headlamp grille, curvy body, elegant recessed backlight, refined tail, and spare use of chrome is a styling high point for late '60s muscle cars. It isn't cheap to buy a used Hemi Charger of the ’68–70 vintage. Hagerty suggests a #1 concours 1968 Charger R/T with Hemi is trending around $185k. This example crossed the block at Mecum.

1968–70 Dodge Charger (Hemi) on the rise

Leading the charge in the latest Hagerty price guide with a 15% hike is the 1968–70 Dodge Charger with hemi powerplant. Dodge gave the Charger a redesign for 1968, and it was a hit. The Coke-bottle shape popularized the muscle car’s golden age. Most famous as the bad-guy car in Bullitt and the good-guy car in The Dukes of Hazzard, the second generation Charger could be had in base, R/T, and 500 trims. Top dog is the hemi.

1956 Maserati A6G/54 Berlinetta

The 1956 Maserati A6G/54 Berlinetta featured a 1,986 CC DOHC Twin-Plug Inline 6-Cylinder engine with 3 Weber 40 DCO3 carburetors, producing 160 BHP at 6,000 RPM through a 4 speed manual gearbox. 4-wheel hydraulic drum brakes. Independent-wishbone front suspension. Live rear axle with longitudinal leaf springs. This Zagato-bodied Maserati is the last of its line, number 21 of 21.

The car sold for $4.4m against an estimate of $4m to $5m in 2017. A concours #1 car was a bargain $3.55m in 2024. Here
