US marshals are to auction a major collection of muscle cars, including a rare 1970 Plymouth Hemi Superbird, at AJ Wilner auctions in New Jersey on September 12.
The lots were formerly the property of David Nicoll of Biodiagnostic Laboratory Services, who was convicted in 2013 of bribing doctors.
 The Superbird is a modified version of the Road Runner |
The Superbird is essentially a heavily modified Plymouth Road Runner and was introduced for the 1970 stock racing season.
It features a decal of the character on the huge back spoiler along with a horn that produces the famous "meep meep" sound effect.
Only 1,920 were ever built and its wild design proved unpopular among buyers, most of whom preferred the more conventional styling of its predecessor.
While the sale doesn't indicate an estimate, comparable examples regularly sell for around $100,000-$200,000 - although one made $550,000 at Barrett Jackson's Scottsdale auction earlier this year.
A 1970 Ford Mustang Boss 429 is also likely to sell for between $100,000-200,000.
The lot is among the most desirable muscle cars in the world and one of the rarest in the Mustang family with only 859 ever built.
It was built around the enormous Boss 429 engine, Ford's first attempt at a Hemi system.
The chassis was substantially reinforced to take its weight, resulting in a model capable of delivering 600 horsepower and speeds of up to 175mph.
