Actually, being made in 1988 makes sense. The Stuttgart team started in 1989 so the frames were likely made in 1988 to be ready for the start of the season. I don't think its a repaint.. It's got chrome dropouts and chain stays with pin striping where the paint meets the chrome. I've chipped the paint in a few places and there is no other color underneath, The Corsa Extra sticker looks original too. Maybe the black lug cutout was a paint error?
