In October, RM Auctions will offer the Charlie Thomas Collection for sale in good ol’ Dallas, Texas.

Well-known by automotive enthusiasts, the collection is the product of two decades of careful and dedicated acquisition by prominent Texas businessman and lifelong auto enthusiast, Charlie Thomas.

A prolific car dealer and former owner of the Houston Rockets, Thomas operated more than 40 car dealerships, one of the largest dealership networks in the United States.

His ‘Texas-size” collection of American motorcars spans the spectrum from American classics to early flatheads, ’50s convertibles, and ’60s muscle and sports cars.

Here’s one of our faves: a rare 1971 Ford Mustang Mach 1 429 Sportsroof.

We call it the “Red Devil”…
