Boss Mustang Flexes its Muscles at Bonhams Simeone Auction

A restored and as new 1969 Ford Mustang Boss 429, which has covered fewer than 3,500 miles in more than 50 years, will lead a host of muscle cars crossing the block at the Bonhams Collectors' Motor Cars and Automobilia Auction to be held on Sunday October 11, at the Simeone Foundation Automotive Museum in Philadelphia. It will be the first fully-live auction hosted by the Bonhams US Motor Car department since the Amelia Island auction.

Not just the most powerful Mustang but the most powerful Ford production automobile of the 1960s, the Boss 429 is considered one of the rarest and most desirable muscle cars of their golden age. The Blue Oval's answer to the Chrysler 426 Hemi engine, the Boss was powered by a 7.0 liter V8 unit that had an advertised horsepower rating of 365hp (to comply with insurance limits) although the actual output was nearer to 465hp.

Originally created to homologate Ford's 429 NASCAR racing programme, fewer than 1,400 examples were built.

Beautifully restored by marque expert Bob Perkins, this example is finished in striking red paintwork with a black interior. It has been in private ownership for more than 35 years and is offered with its original window sticker, Kar Kraft inspection sheet and original Boss 429 Manual. Estimate $250,000 - 300,000.

Lining up with the Boss are 11 other all-American automobiles, all offered by one private collector, representing the great domestic manufacturers: Buick, Dodge, Oldsmobile, Plymouth and of course Ford.

Among the collection are two particularly noteworthy muscle cars: a 1971 Oldsmobile 442 W-30 and a highly collectible 1969 Buick GS 400 Stage 1, both with an estimate of $80,000 - 100,000.


1971 Oldsmobile 442 W-30, estimate $80,000 - 100,000

General Motors' Oldsmobile division originally prepared the 442 as a performance option on its Cutlass model - and then built it as a model in its own right from 1968. The 442 referred to the car's combination of four-barrel carburetor, four-speed manual transmission and two exhaust, with power provided by its 455 V8 engine.

The 442 was blessed with the most desirable options, such as the performance-boosting W-Machine package, which was fitted to only 810 cars in 1971, including this example, which is also one of just 247 cars to benefit from the close-ratio race bred M22 "Rockcrusher" Muncie 4-speed transmission, again only available in 1971.

As well as the standard bucket seat, custom steering wheel, this 422 is packed with a superb array of options: anti-spin rear, vari-ratio power steering, heavy duty performance axel package with 3.73 to 1 ratio, soft-ray tinted windshield, Super Stock 1 wheels, custom-sport steering wheel and a rear deck air spoiler to go with the lightweight fiberglass hood with dual force-air intakes.

Documented with its original window sticker, the 442 has been restored to its former glory by a marque specialist.


1969 Buick GS 400 Stage 1, estimate $80,000 - 100,000

The 1969 Buick GS 400 Stage 1 coupé has similarly undergone a specialist restoration and to such a high standard that it is a former Buick National Concours Gold Award Winner.

Advertised in period by Buick as a 'premium performance machine', the Stage 1 option offered increased power by nearly 50hp, thanks to a high-lift camshaft and cool air intake system indicated by the trademark hood scoops, with a heavy-duty Rally suspension and power disc brakes to match.

This particular car also benefits from numerous authentic period Stage 2 components, which were fitted to the car in its early life during its racing career. These include early prototype stage 2 development heads – one of only 75 sets produced for purchase by the public, as well as a set of vintage Kustom Headers by the Kustom Equipment Company of Michigan produced for Buick. Additionally, the 455 block contains Stage 2 TRW pistons with Sealed Power rings.

Greg Porter, Bonhams Head of Sale, said: "We are so pleased to offer this unique gathering of some of the most famous and awe-inspiring muscle cars to Simeone. They will provide an interesting contrast to the brass-era and vintage automobiles that we are traditionally known for bringing to Philadelphia."

Other highlights of the sale include:

1934 Lagonda M45 T8 Tourer, estimate $150,000 - 175,000

One of 10 known survivors of the classic pre-war British Grand Tourer, this motor car has been in the ownership of the same family since 1967.

1913 Locomobile Model 38, estimate $240,000 - 260,000

A five-passenger touring car produced by one of the most prestigious US manufacturers of pioneer motor cars.
