1949 Rocket 88
1949 was the 33rd running of the Indy 500 and Oldsmobile's first time serving as the official pace car. The car was a 1949 Rocket 88 driven by Sam Hanks. As far as I know no replicas were produced since the pace car was the same as could be bought at a dealership except for the Indy 500 decals.
