I know this off-topic, but not entirely. A car enthusiast is someone who sees their car not as liability or necessity but as a means for personal enjoyment. It doesn't matter if a person guts the car and races, adds stereo and video equipment, leaves it stock and keeps it sparkling clean or just puts on stickers it; if they are getting enjoyment out of what they do with their car, they are an enthusiast. While we all have our own favorite way to express our enthusiasm, we all share a passion for our cars.
And this is, tangentially, why I really hope that SCT or someone gives us the ability to tune our cars. There are so many different types of enthusiasts who will benefit from the ability to tune the car. From people who want to autocross a car that is otherwise stock to those who to see if they can make a 200 whp steet toy without internal mods to those who want to build a 500 hp drag monster. Tuning is a benefit to all.
