Mass Pike Fastlane and NY/NJ EZPass require license plate transponders instead of the internally mounted windshield ones for certain cars that have some weird glass chemistry. My '02 Bonneville was in that category, and evidently so was the 2000-03 GP. Those agencies haven't even heard of the '04 GP yet, so they don't know if the internal transponders will work, but they prefer them for several reasons which aren't relevant here. My question is, does anyone know if the '04 GP has that same requirement as the '03?
