Many enthusiasts participate in car shows and races, showcasing their tuner cars and competing for recognition. Popular models for tuning include compact cars like the Honda Civic and Subaru WRX, which are known for their potential to be modified. The tuning community often shares tips and techniques through online forums and social media.
