The dream of California engineer Milt Brown, the International Motor Cars Apollo was Brown's answer to European GT cars of the 50s and 60s — specifically those of Aston Martin and Ferrari. Brown met Frank Reisner who founded Intermeccanica and contracted the coachbuilding out to Reinser's firm, and the Apollo was born. Released in 1963 with a 3.5-liter Buick V8, the Apollo 3500 was praised for its handling and power beautiful lines. 42 were made before the original production run stopped, although cars were built by various other companies in the years following. This 1963 Apollo 3500 GT Spider is one of the originals and is being auctioned with a fellow 1963 3500 GT coupe and larger-engined 1966 5000 GT coupe. An excellent example of American-European auto partnership, these Apollo GTs are a rare opportunity for a classic sports car collection.
