So what spec have you gone for, and how far through the process are you?
I've gone for the 3dr PP in Pure White, manual, tinted windows and Dynaudio. Everything else standard.
I'm big into my audio and as you say it seems to be worth the upgrade especially when a lot of the nicer speaker kits for other cars are costing over 2x what VW charge. IMO you'll never again be so bothered if your drive home takes an extra 20 minutes as you'll have been listening with a smile on your face.
Ordered 12th Feb, they said est mid June. Already got confirmed build week 26/3 so thinking their estimate was a little slow, I'm reckoning on having it for 1/5.
