1969 Ford Mustang Boss 429

The Boss 429, the 'Boss 9', is one of the rarest and most valued muscle cars from the era.

The origin of the Boss 429 came about as a result of Ford’s desire to compete in the top NASCAR series. Ford was seeking to develop a "Hemi" engine that could compete with the famed 426 Hemis from the Mopar camp - the 426 Hemi Charger Daytona and the Plymouth Superbirds. The Boss 429 ci OHV V-8 engine was rated at 375 HP while actual output was well over 500 HP.

In 1969 there were 859 Boss 429s made by Ford, two of which were Cougars for the Lincoln/Mercury Race Division. There were five different colors available and the only color for the interior was black.

#1 Concours examples trended around $455k in 2025 according to Hagerty. Condition #1 vehicles are the best in the world.

In 2015 a 1969 Ford Mustang Boss 429 with a nearly unbelievable 120 miles on the clock sold for $247,000 That number would be much, much higher today.

KK No. 1857 brought $231k at Mecum's in 2019. Prices have exploded in the past 5 years.

1937 Bugatti Type 57 Atalante

The Atalante was a two-door coupe body style similar to and built after the Atlantic, both built on the 57S chassis.

Only 17 Atalante cars were made, four of which reside in the Cité de l’Automobile Museum in Mulhouse, France. One of the most aerodynamic and beautiful of Bugatti’s Type 57 variants, the car was capable of 125 mph with its 3.25-liter inline-8 that produced an unheard of 175 hp. The Type 57S is equipped with a Marshall K200 supercharger, 4-speed manual gearbox, and 4-wheel mechanical drum brakes.

The engine on chassis 57502 was fitted with a supercharger by its second owner. This gave it a mind-boggling 220 hp.

The Type 57S is one of the most sought-after of all Bugattis.

This 1937 Type 57S Atalante sold for £7,855,000. ($10,179,000)

These cars don't appear for sale often. When they do the price is over $10m. In 2009 a rare, unrestored 1937 Bugatti Type 57S Atalante Coupe was found decaying in the garage of a British doctor. He died in 2007, and reportedly had kept the vehicle parked in his garage since the early 1960s and hadn’t driven it in five decades. A month later the car sold at a Paris auction for some $4.4 million.

Torque is 590 pound-feet, and McLaren says the dry weight is 2789 pounds. Powerplant revs to 8500 rpm, with power peaking at 7500 rpm. McLaren claims 60 mph in 2.8 seconds and 124 mph in 7.0 seconds flat.

1971 Dodge Hemi Charger R/T

One of the very last 426 Hemi models built was the 1971 Dodge Charger 426 Hemi. The 426 Hemi was offered one last time on a B-body vehicle for an eye-watering $746.50. The muscle car cost $3,777 before options. A scant 63 of the over 50,000 Chargers sold that year were fitted with the monster 425hp V8 powerplant.

1 of 63 Hemi Charger R/Ts produced in 1971. 1 of 12 produced for the Canadian market. 1 of 30 Hemi 4-speed Charger R/Ts for 1971. Matching numbers drivetrain. 426 Hemi V-8 engine. Dual 4-barrel carburetors. Hemispherical cylinder heads. Dual exhaust. A833 4-speed manual transmission. Dana 60 Super Track Pack with 4.10 rear axle. Power steering. Power brakes. Ramcharger hood with hold-down pins. B5 Bright Blue Metallic with Black R/T striping. Front and rear spoilers. Blue vinyl bucket seat interior. Hurst Pistol Grip shifter.

A final year Hemi Charger R/T is a prime collectible. In a model season that saw just 63 Hemi Charger R/Ts produced overall, this car is a top-notch example with the legendary 426 Hemi V-8 engine, dual 4-barrel carburetors, hemispherical cylinder heads, high-flow dual exhaust and heavy-duty suspension and cooling equipment. Coded A34 for the Super Trak Pak, this Charger has the highly desired performance-engineered A833 4-speed manual transmission coupled to a 4.10 Dana 60 Sure Grip rear axle.

The ‘71 Charger R/T Hemi with a four-speed and the Super Track Pak could reach 60 mph in 6.5 seconds and trip the quarter mile in 13.73 seconds at 104 mph.

When the 426 Hemi was introduced in 1964, it was strictly a racing engine. That year, four Hemi-powered Mopars swept the Daytona 500, finishing 1-2-3-4. It caught the racing world by surprise, and prompted NASCAR to impose stricter production rules on Chrysler. Instead of producing a few blueprinted Hemi motors each production year, they would have to produce several thousand and sell them in street-legal cars. Four bolt mains were standard on every 426 Hemi, street or race. The motor was essentially ruled out of NASCAR in the 1970s, and emissions laws, production costs, and insurance surcharges ended the street version after 1971.

A true muscle classic, this car made $181k in 2019. Hagerty suggests a concours 1971 Dodge Hemi Charger R/T is trending around $303k today.
