At the 2008 Mobil 1 12-Hours of Sebring, the Historic Trans-Am Group made their first visit to Sebring International Raceway. The Historic Trans-Am Group was created to recreate the original Trans-Am series from 1966 to 1972.

Only cars that competed in the series from 1966 to 1972 are eligible to join the group and proof is required. Historic Trans Am cars may be restored but must not be upgraded. Replacement components must be the same type and style; however, modern materials are encouraged to promote safety.
