BILL MITCHELL’S BUICK CENTURY X, created at GM Styling, will make its international Concours debut in the Amelia Concours d’Elegance’s on March 8, 2020.

BILL MITCHELL’S BUICK CENTURY XBill Mitchell was Harley Earl’s handpicked successor at GM Design and Styling. Their association seemed to go beyond the standard boss-employee dynamic. Many called it a father-son relationship. Mitchell was just 23 when Earl appointed him chief designer of Cadillac. His design of the ‘38 Cadillac 60 Special was a landmark. But Mitchell was a “Buick man”. His father was a Pennsylvania Buick dealer, and despite being the design prodigy given the reins of the Corporation’s premier car division and style leader, Mitchell ached to draw Buicks. In 1954, Mitchell, right, with the iconic ’65 Mako Shark Corvette, became GM’s Director of Styling, working under Harley Earl.

BILL MITCHELL’S BUICK CENTURY XMitchell drove over 50 “personalized” vehicles during his GM career and was best known for his love of Corvettes and Camaros. But his heart belonged to Buick and, in 1956, he created the customized ’56 Buick Century X. It wasn’t a landmark dream car like Earl’s Buick Y-Job or the ‘51 GM Le Sabre, but a modified production car – special order 90022 – a true factory custom.

Buick auto show cars were the glamour models of the Corporation. Much was expected from the Century X; Buick delivered. Mitchell’s 225 changes were more subtle than startling, hardly the usual fare for a GM “dream car” of the 1950s. Dual side exhausts exited through the rocker panels requiring holes cut in the frame with plates welded around the openings for added strength. Century X also wore twin telescoping power headrests, swivel bucket seats, plush carpeting, Skylark-style wire wheels, Mitchell’s signature red chassis, and a prominent tachometer. Chrome accelerator and brake pedal trim told anyone who knew the design section’s secret internal language that this was indeed BILL MITCHELL’S BUICK CENTURY X.

BILL MITCHELL’S BUICK CENTURY XBeing a racer at heart and taking a page from his mentor’s corporate playbook, Mitchell had the Century X driven to Elkhart Lake, WI for the Road America races in 1956. His timing was good. A new V-8 Corvette – another Mitchell favorite – defeated a field of Jaguars to notch the mighty Corvette’s first victory at Road America. Mitchell spent the race weekend cruising around the resort village much as Harley Earl had done at Watkins Glen during 1951 Grand Prix week with the Le Sabre dream car. Bill Mitchell spent 42 years at GM, working his way up to Vice President of Design, a position he held for 19 years. He retired in 1977 and opened up William L. Mitchell Design, a design consultancy he ran until really retiring in 1984. He passed away in 1988.
