(AP) — Fast sports cars with sleek, sexy lines are the last thing passers-by probably imagine when they pass the nondescript metal building in an industrial park in northwest Alabama. The company collects, sells and exports Porsches of all makes and models on the international market. Trissl started another flooring company and the Porsche business. Dan Barger, of Florence, who owns a 1985 911 Coupe and a 2003 911 Cab, said Trissl has an impressive collection. Schurfeld said the car is one that Porsche used to take to automotive shows. Porsche will make any exterior and interior colors for their customers, which explains the purple car with purple interior, a 911 C4. Remember the car Tom Cruise put in the water in the movie "Risky Business?" Trissl has a version of it, a 928 GTS. In another showroom, there are two Porsche race cars — a 1963 Formula B race car and a 1986 944 LeMans-style car. In addition to its Internet presence, Trissl advertises in Porsche magazines and attends all Porsche car shows in the U.S.
