Hi, I need an expert here. I've got a roundtail eurospider that I'm selling. Power brakes, 1750, dual webers, all that. Problem is one of my potential buyers is asking weather it's really a 69. He says someone he checked the VIN with claims its a 1971 eurospider. Previous title and registration said 1970, which made sense as my '66 Duetto's title says '67 on it, but I thought '69 was the last year for the roundtails. Why would it be listed somewhere as a '71?
