The car up for sale is a 1970 Ford Mustang Boss 302 that carries a tiny, unexpected detail: the dashboard bears the signature of former Trans-Am driver George Follmer.
Unique Features of the 1970 Boss 302
Ford introduced the Boss 302 in 1969 alongside the Mach 1 and the high-output Boss 429, aiming to meet the revised Trans-Am series rules.
The model replaced the rear-quarter “air scoops” with a front spoiler and a rear deck wing, becoming the first production car to combine both aerodynamic devices.
Standard equipment included a custom stripe package, a shaker-hood scoop, and a Hurst shifter that became mandatory for 1970 models. The shaker-hood scoop also served as a visual hallmark that identified the high-performance version.
That year the car also received hockey-stick side stripes and an optional black hood with rear-window louvers.
The powerplant was a 302-cubic-inch (5.0-liter) V8 built on a thin-wall small-block casting, featuring solid lifters, four-bolt main crankshaft bearings, and threaded compression freeze plugs.
Its cylinder head used a canted-valve design to accommodate larger valves later used on the 351 cubic-inch Cleveland V8.
Ford rated the engine at 290 horsepower, matching the output of the rival Chevrolet Camaro Z28.

Production in 1969 totaled 1,628 units; the 1970 run increased to 7,013 examples, still far fewer than the Camaro.
Only 352 of the 1970 cars were ordered in Grabber Green, a color that adds to the vehicle’s collectibility. This limited-run hue is prized by enthusiasts who seek a rare factory finish.
Provenance and Auction Prospects
The Nashville example has undergone a concours-level restoration, with factory-correct paint and reproduction markings that match the original specifications.
It retains the original numbers-matching engine and a four-speed manual transmission, and it is accompanied by a dealer invoice, original window sticker, and an Elite Marti Report.
Inside the cabin, the dashboard bears the autograph of George Follmer, a celebrated driver who won four Trans-Am races in a Mustang between 1969 and 1971.
Follmer helped Ford capture the 1970 Trans-Am championship after a two-year hiatus, later winning titles in the AMC Javelin, Porsche 934, and the 1972 Can-Am series.
The vehicle will be offered at the Mecum auction in Nashville on September 26, 2026.
