paint colors for all years
Looks like the 2000 is vapor blue. So the 05 is a 2.0 and the 2000 is a 1.8T?
The one you are meant to have will choose you.
What about service records? Regular oil changes? I searched for "automatic" on the org and it looks like they need the fluid flushed every 40-60k. VW says it's a lifetime fluid but some owners would disagree.
