At its current (as of this writing) bid of $7,700 I'd say its worth it because it'd be difficult to build it for that. I didn't see any write-up or details listed, and I'd have to know more before bidding.
A '76 in the States would make it a 1.8 car, but anyone's guess what's there now. Looks good with its dual IDFs in place.
That panel fit shown on the right rear is odd to me. How do you not see this problem as you're doing body & paint on the car? I'm sure there's an answer... It'd be a very fun event car but without the Abarth IRS set-up, diff, & 16v head, it'll always be more of a donkey than a thoroughbred. Wouldn't kick it outta bed though ; )
Having driven both, I'd prefer an Alfa Sprint Veloce with some Autodelta styling bits to this any day.
