It's been to Daytona, but it is not a Daytona prototype. The cars known these days as Daytona Prototypes started in the '90s and are some of the ugliest cars ever built. The France family *ruined* the Rolex 24 when they changed the rules to have the same body, different engine.
That said, the car *is* a prototype, and I believe it has been to Daytona, considering this cousin has been to Daytona in many different cars.
