Yeah Scharf is right. The last Vin I saw for a MK VI GTI was from Wolfsburg. This site has old info on VW vin's but I am guessing not much has changed.

Here is the General rule:
First digit is for the Manufacturing Country. If it starts with a W then its from Europe, 1 is USA, 3 is Mexico, 9 is Brazil.
Second digit stands for the Manufacturer. A is for Audi, B is for VW Brazil, and V is Volkswagen.
Eleventh digit is for the Assembly Plant. A - Ingolstadt, B - Brussels, E - Emden, G - Graz, H - Hanover, K - Osnabruck, M - Mexico, N - Neckarsulm, P - Brazil, S - Stuttgart, V - Westmoreland, PA. (USA), W - Wolfsburg, Y - Spain (SEAT)
Here are two vin numbers from 2010 Volkswagen Golf's on eBay. I'm going to X out the serial numbers.
2010 Volkswagen Golf GTI:
WVWEV7AJ3AWXXXXXX = VW Europe, Wolfsburg.
2010 Volkswagen Golf 2.5L:
WVWAB7AJ6AWXXXXXX = VW Europe, Wolfsburg.
Mongo I say go with your gut, if your not willing to wait for the R20 then pull the trigger on the GTi.
