This is what I found about my Audi on the web...
"1987 was another strange year for the Coupe. The first half of the year yielded the regular '85-'86 style Coupe GT with 2.22L engine and analog dash. According to Jeff Goggin, Audi started production on a Special Build Coupe GT in 2/87. According to the catalog produced by The Parts Connection, VIN 85-H-023684 was the first Special Build car. Instead of the 2.22L engine, these cars used a larger 2.3L 130HP engine with a compression ratio of 10:1 and knock sensing ignition. It also incorporated and orange version of the digital dash which was used in the 1986 Commemorative Edition Coupe GT. Audi made several changes to the outward appearance of the car, painting the rear spoiler and window trim the same color as the body of the car. The '87 Coupe also replaced the rear drum brakes with disc brakes."
