The SevanSeries Trans Ams are dealer customs assembled by Evans Pontiac. I was told that there are only around 30 Sevan Series Trans Ams to date. The "Sevan Series" name is a tribute to "Steve Evans," the owner of Evans Pontiac. Other than the Mecham TA, this is probably one of the most powerful Trans Ams available from a dealer lot that isn't a trade. Sevan Series cars dyno at approximately 360 Horses on the motor, which is 15 more than a stock Corvette C5.
