Hope I Helped and happy hunting - T0X1C

There are 3 types of cars: Sport, Muscle and Truck.

When playing the Championship mode the 3rd championship requires you to choose a car from the Sports categorie. After playing the championship, which consists of 3 races, you will unlock this achievement.

Note: to unlock the 3nd championship you need to finish the 1st and 2nd (I don't know if you need to win them)
