At the completion of the 1991 season, the Hylton Motorsports Buick LeSabre was rebodied as a 1992 Pontiac Grand Prix by crew chief Terry Strange.  The first appearance of the 1992 Grand Prix was Daytona's Gatorade Twin 125 where James Hylton piloted the car to a 25th place position.  Hylton and the #48 Grand Prix competed in eight Winston Cup events during the 1992 season with a best finish of 25th coming at Michigan's Miller Genuine Draft 400.

During the early nineties, multi-car teams began dominating NASCAR and under-funded teams like Hylton Motorsports began having a harder time making races.  Hylton qualified for two races during the 1992 Winston Cup season, Rockingham's GM Goodwrench 500 and Darlington's TransSouth 500 while teammate Trevor Boys competed in Pocono's Champion Spark Plug 500.  Boy's Pocono start would mark the final time the familiar #48 Hylton Motorsports entry would compete in a NASCAR Winston Cup Series event. Hylton Motorsports had recorded 707 NASCAR Grand National/Winston CUP starts with the number 48 since the 1966 season.

The 1994 season started off with Trevor Boys piloting the Grand Prix to a 21st place finish in Daytona's Gatorade Twin 125, which unfortunately did not put him in the Daytona 500.  This would mark the lone start for Hylton Motorsports during 1994 as the large corporate teams began to dominate the sport.  In 1995, Hylton would drive the #48 Grand Prix to a 29th place finish in the Gatorade Twin 125 and a 27th place finish in the Charlotte's Winston Open.    The number 48 would be dormant in NASCAR until the 2001 season when it would be ran by Jimmie Johnson and Hendrick Motorsports.

The Hylton Motorsports Grand Prix moved to the ARCA RE/MAX Series in 1997 with driver Jim Lamoruex behind the wheel.  Lamoruex raced the car to an impressive  13th place finish in Talladega's Winn-Dixie 500K, four laps down to winner Tim Steele.  Lamoruex recorded two Top-25 finishes before destroying the car on the first lap of Atlanta's Georgia Power 200 on August 28 in a incident which claimed the life of Greeneville SC's Chad Coleman.  The long-serving chassis was stripped and sold for scrap after completing 14 years of service for both the Stavola Brothers and Hylton Motorsports.
