That orange was popular, my parents' '72 Lemans GT was the same shade of orange.
Your "driver" restoration is very sanitary, the '68 H/O must have been stunning.
Sorry your appraiser experience was poor. It's a wide open industry, and you really have to interview people to make sure they're up to the task. Some of us do know what we're doing, however
Here's a link to that green '72 W30 for sale up here in the Pacific NW. Not nearly as cherry as the one featured here, but a fun color and a 4sp as well.....
