One of the easiest achievement. As soon as you completed as little as a single race with a podium finish, you will have enough money to buy a cheap customization option like a wheel (2000 dollars). Just start any online race selecting your customized car, you can do this in a private session with a friend or in public matches alike. The achievement will pop up during the countdown for the race's start, you don't even have to reach the finish. You will want to finish it because there's an achievement for completing a race, too.
