The Big Sellers

1969 Ford Boss 429 (Lot #423)

SOLD – $550,000

Taking the top spot in sales this weekend was a classic Mustang Boss 429, one of just 859 created in 1969. Absolutely immaculate from head to tail, this particular semi-restored example (the 170th model produced) came with all the right paperwork and the original Raven Black paint job. Under the hood, you’ll find magnesium rocker covers, bigger valves, and NASCAR connecting rods, all of which are exclusive to the first 279 Boss 429s built.

2006 Ford GT Heritage Edition (Lot #401)

SOLD – $467,500

Believe it or not, there were actually two of these beauties in Palm Beach, with Lot #401 joined by its sister car, Lot #426. Both came in a striking Gulf Oil livery, which gives a nod to the Le Mans-winning GT40 racer that took it to the Europeans in 1968 and 1969. Lot #401 managed to carry a $55,000 premium thanks its outrageously pristine condition, which included shrink-wrapped seats, factory transport stickers, and less than five miles on the odometer.

1957 Ford Thunderbird F-Code Convertible (Lot #386)

SOLD – $193,600

Also known as the “F-bird,” this example was fitted with a supercharged F-code engine, producing 300 horsepower from 312 cubic inches. Outside is a rare Flame Red paint job, while inside is matching red upholstery. Memory seats, power windows, and a Town & Country radio make the options list, as does a soft-top assembly and porthole hardtop.

1967 Chevrolet Corvette 427/400 Convertible (Lot #375)

SOLD – $181,500

Still bearing its original 400-horsepower 427 engine, this ‘Vette also offers the rare color combination of Ermine White exterior paint on red leather upholstery (it’s said just 34 red leather cars were produced in 1967). Fully restored, there are Kelsey Hayes bolt-on wheels in the corners, completing this highly desirable classic American sports car.

2017 Chevrolet Corvette VIN #001 Grand Sport (Lot #3003)

SOLD – $170,000

To help raise money for charity, GM donated a couple cars for the event, including this first-ever 2017 Corvette Grand Sport. An LT1 V-8 is nestled into the nose, offering up 460 horsepower and 465 pound-feet of torque, while Watkins Glen Grey Metallic and Tension Blue paint covers the upgraded aerodynamics. The bruiser color scheme continues inside the cabin as well.

2017 Chevrolet Camaro VIN #001 50th Anniversary

SOLD – $150,000

Following the brand new ‘Vette was a brand new Camaro, also the first of its line to be produced. This special edition commemorates five decades of muscle car greatness with unique touches inside and out, like 20-inch wheels, orange brake calipers, black leather upholstery, and illuminated sill plates.

Failed To Sell

1957 Ford Skyliner F-Code Retractable Hardtop (Lot #387)

DID NOT MEET RESERVE

This thing just screams Americana. With a 300-horsepower, supercharged V-8 engine, automatic transmission, and styling that goes on for days, this red cruiser is positively loaded with accessories, including a Town & Country radio, Continental exhaust, and back-up lights. It’s also extremely rare, being one of just seven models produced that combine an F-Code engine and retractable hardtop roof.

2005 Porsche Carrera GT (Lot #400)

DID NOT MEET RESERVE

Before the 918 Spyder, there was the Carrera GT. The zenith of Stuttgart performance in its day, the Carrera GT got a 5.7-liter V-10 crammed behind the open cabin, which mates to a six-speed manual transmission and sends a very healthy 605 horsepower to the rear axle. This particular example came with a red exterior and black interior, with 2,724 miles on the odometer.

DID NOT MEET RESERVE

No major car auction is complete without a jaw-dropping Prancing Horse – in red, please. This one’s equipped with a 300-horsepower V-12 engine and five-speed manual transmission, plus a design from Pininfarina. It’s also got air conditioning (a factory option), plus four-wheel disc brakes.
