Enjoy it. Remember. Tuning isn't always spending more money to keep up with the jones. It's not about how much it takes to make it in euro mag. It's about loving the car. If anything you should help your brother get out of that rice burner he's got. Instead of the latest LED glow stick, perhaps you could buy your brother a VW shirt that says something like "forgive me, I don't know any better". Take it easy and keep loving the VW.
