I just went to byers...........The 0% is for 60 months and only on 08 GTIs. They had two identical cars, DSG(auto), 18" wheels sunroof etc for 25,800 ish sticker.
A base model 6 speed is about 23k, with 22k being doable for the car pre tax. meaning payments would be around 365 without tax.
Wholesale dealers (not sure what dealers are, but byers is NOT) can do 0% for 72 months.
