The Bottechias from the mid to late 80's did have tapering upper seat stay ends that semi-wrap around the front of the seat lug, as you can see on my 1989 Bottechia Professional Chorus SL:
I suspect that. the subject bike is the model right below mine and might have Cromor tubing. But I definitely think it's a genuine late 80's Bottecchia. And could be an 89 like mine.
Price is a bit high for a mid line model. Maybe $400.00, max, if in mint condition. More like $350.00 in "rider" condition. Less if the components are not all original, like on the subject bike.
