Speed Buggy was a 1973 Saturday morning cartoon produced by Hanna-Barbera Productions. A direct clone of Hanna-Barbera's successful Scooby-Doo, Where Are You!, Speed Buggy followed the adventures of an anthropomorphic race car, Speed Buggy (voiced by Frank Welker), his driver Tinker, and Tinker's friends Mark and Debbie. The three young adults and their car traveled from race to race, often encountering spy capers and mysteries along the way.
