Here's a 2-door Bonny I could live with, if it had a Pontiac engine. A 400 was available in a '77 & '78 model Cat & Bonny.

Remove the fender skirts and put the right wheels and tires on it and it could look decent.
Here's one with a 400, but it has the half vinyl Landau roof I don't like. Just gives 'em a different look.

Don't really like green or vinyl tops, but this '71 Lemans looks good. The reserve will put it out of reach.
