Haven't started yet, just got a growing list of things to do.
HID's will be fitted next time it in for a service in a couple of week, and then thinking of putting the RS6's from my A4 onto her bug (if they fit) and buying myself some new rims for mine, haha.
Exhaust wise i reckon they both woulf look good but personally would go for the twin exit option. With the spoiler it would look awesome, cause the arse of the Beetle looks very plain and boring and would even both sides out making it look wider and more aggressive.
What option do you prefer?
