A Roush-built promotional F-150 that sold for $41,800 in September is back on the market, and so far the bidding is running below that figure. At the time of writing, the high bid on Bring a Trailer is $33,500, with 19 bids placed. That is $8,300 under the September price. The auction ends at 2:45 p.m. Eastern on Friday, November 13. A dealer in Fort Lauderdale, Florida, is selling the truck. The truck in question is a 1990 F-150 XLT Lariat, a short-bed 4×2 that Roush Industries modified when new. It is said to be one of two built for promotional use by Roush Racing. It was held in the Roush Family Collection before 2026 and shows 12,000 miles on its mechanical odometer.

The red, white, and blue livery is joined by rocker moldings, grab handles above the sliding rear window, and a roll pan. The 5.8-liter Windsor V8 has Trick Flow Specialties aluminum heads, custom intake components, Crane aluminum rocker arms, high-rate Crane valve springs, and a Crane hydraulic roller camshaft. A sport-tone exhaust with catalytic converters completes the engine.

Power then goes through an aluminum driveshaft to an 8.8-inch rear end with a limited-slip differential and 3.55:1 gearing. The lowered suspension uses dropped I-beams, an underslung rear axle, and larger-diameter sway bars. Four-wheel disc brakes provide the stopping power, and 17×9.5-inch Center Line wheels carry 315/35 Goodyear Eagle GS-C tires. The Interior The blue cabin has a roll cage, contoured bucket seats, and Simpson cam-lock harnesses. A Grant GT steering wheel sits in front of a 180-mph speedometer, a 9,000-rpm tachometer, and auxiliary gauges. Air conditioning, power windows, color-keyed carpets, woodtone trim, a center console, and a cassette stereo are also included. The dealer serviced the air conditioning with refrigerant and notes that the stereo's volume button is finicky. Paperwork and condition The sale includes a build sheet, a racing glove, owner's manuals and a clean Carfax report with no accidents or damage reported. The title is from Montana, and its odometer entry reads "Exempt." The dealer's walkaround video shows blemishes on the front bumper and other flaws. Image Credit: Bring a Trailer
