Buick Centurion

Buick introduced the Centurion in 1971, replacing the Wildcat as its sporty full-size offering. Slotted between the LeSabre and Electra 225, it shared GM's B-body platform but had its own unique grille and trim. All Centurions were V8-powered, initially with the 455-cid big-block as standard, though a 350-cid V8 became the base engine later.

The Centurion's production run was brief, lasting only until 1973. This short lifespan makes it a relatively uncommon sight compared to its Buick stablemates. Collectors are drawn to its unique place in the Buick lineup and its representation of the final years of the traditional American convertible and full-size coupe. It's an accessible way to own a stylish land yacht from the early 1970s.

With only 12 sales tracked, the market is small, and values are modest. The average price of just over $12,000 makes the Centurion an affordable classic. Convertibles consistently bring higher prices than hardtops and sedans, with top examples pushing past $20,000 while project cars can be found for under $6,000.

Prices range from about $5,400 for cars needing work to over $20,500 for excellent examples.
