Not bad if it is as it says and if the workmanship on the resto was quality. You couldn't buy/restore one for that unless doing nearly everything yourself.
Left valve cover looks to 74-75 with oil filler in the center of the cover . I would park that in my garage anytime!!!!!!!!!!!!!!!!! Bill
Looks like a really nice stage 1 convertible, honest question how many pictures are you a loud in a eBay ad ?
I believe the guy just "fat-fingered" the huge bid. He retracted it and then placed another bid, minus one of the fives.
Nope, he did it on purpose to see what the reserve was, and then tried to act like it was an accident.
