Identifying a Campaign - To qualify as a true Campaign GTI, the car should have the following features:

1. Registration; must be an A-reg, or later. Note: some A-reg GTIs are not campaigns, so you cannot validate them by the index number alone.
2. Vehicle Identification Number (VIN); the number of your chassis will be absolute proof of whether it's a campaign (or was originally). Look at the ID plate under the bonnet, and the chassis number should have the following ID preceding it: WVW ZZZ 17ZEW xxxxxxxx The 17 means it's a Mk1, the E is the date-code for August '83 manufacture, and the W indicates it was built in Wolfsburg, Germany.
3. Factory fitted sliding sunroof.
4. Pirelli 'P' Alloys; 14" Mk1 alloys. The gap between the 'P's should be 7mm. If not, it could be the Mk2 Pirelli's (10mm gap), which are sometimes used on 'fake campaigns'.
5. Factory fitted twin headlamp grille; the extra lights are the foglamps (the glass should have a vertical pattern).
6. Green tinted glass windows.
7. Leather bound steering wheel.
8. Door lock pins; they have a dip in the top, whereas the standard pins are rounded.
9. Fuel cap with spring loaded cover.
10. Limited Colors; Schwartz Black, Alpine White, Mars Red, Diamond Silver, Helios Blue, and Lhasa Green.

Please note that many original campaigns have had various modifications over the years. The most important identifier is the VIN number. This proves the chassis is a 'campaign'. So although a car may not have all the above features, it may have originally been a campaign. The other parts can be restored back to standard, so there's still a good chance of saving campaigns that don't boast all the original features.
