Spring Break Achievement
Drive a 1962 Ferrari GTO on Sebring Full Circuit
This achievement is earned in Free Play using a 1962 Ferrari 250 GTO. From the main menu choose Free Play and in the menu choose "Select Track". Navigate to Sebring International Raceway and choose the Full Circuit configuration. Then go to "Select Car" and choose the 1962 Ferrari 250 GTO. Select "Game Options" and set Game Type to Circuit Race, Drivatars to 1, Drivatar Difficulty to New Racer, and Laps to 1.
Start the race and you will unlock this achievement almost immediately. You do not need to finish the race at that point and can just quit out.
If you choose the 1962 Ferrari 250 GTO as your vehicle of choice for the Racing Icons Championship Series in the Vintage League, this will unlock at the start of your seventh race in the series.
Note that the 1962 Ferrari 250 GTO is the most expensive vehicle in the game and is the only car this achievement can be earned with. If you don't have the money to purchase it, or don't wish to spend the money, there is currently a way to rent it even though typically it is not available for rent. To do this, follow the instructions above and when you get to selecting your vehicle, choose Rent Car and press on the first choice. This will drop you back to the Freeplay setup screen. Choose Select Car again, and this time go to Buy Car. Scroll to the 1962 Ferrari 250 GTO, press to buy the car but at the Recommended Designs screen, press three times. This will drop you back to the Freeplay setup screen again, but you will have the 1957 Ferrari Testa Rossa as your rental. This is a bug in the game and may be patched at some point. If it is patched, you will need to purchase the Ferrari to obtain this achievement.
