Most special-edition Mustangs exist because Ford wanted to sell something. This one exists because a giveaway fell through. A 54k-mile 1990 Ford Mustang LX 5.0 convertible in the 7-Up Edition is bidding on Bring a Trailer, with the auction set to close on October 1 and the high bid sitting around $10,600 at last check.
The 7-Up Edition was a one-year-only package, and its backstory is the best part. According to the Bring a Trailer listing, the cars were meant to be promotional giveaways tied to the 1990 NCAA basketball championship. The promotion was canceled, but Ford had already committed to the look, so it built matching Mustangs and sold them through dealers anyway.
A Mustang Built for a Promotion That Never Happened
Every 7-Up Edition is an LX 5.0 convertible finished in Deep Emerald Green Metallic with a white soft top and white leather. Ford added the handling suspension package with variable-rate springs and Quadra-Shock rear setup, plus cruise control, air conditioning, power windows and locks, and a cassette stereo. Production totaled 4,103 cars, according to Wikipedia's Mustang history and Ford Authority. The count fell short of the 5,000 Barn Finds says Ford originally planned.
The one-year claim holds up because of what surrounds it. The 1990 model year brought the Mustang's first driver-side airbag steering wheel, and 1991 changed the lineup again. No other model year offered this green-and-white 7-Up combination.
The Auction Car
The listed example was delivered new to Tommys Highway Service in Pen Argyl, Pennsylvania. It runs a 302ci V8 with a four-speed automatic and a Traction-Lok rear axle, which makes it the more common configuration: 2,743 of the 4,103 cars were automatics, versus 1,360 with the five-speed. It also rides on 15-inch alloy wheels with a luggage rack and front sport seats. The seller acquired it in March 2026 and is offering the window sticker, a Marti report, owner's manuals, a clean Carfax report, and a Virginia title.
For Fox-body fans, it is a chance to buy a car with a story that has nothing to do with horsepower.
