Where is my 1966 Dodge Dart

How were these rare? Granted, I have never seen one but how many 66 Darts we have on this board? Was it the post option or ...?

PS Wow, Hagerty list the 170 $16,800 in concourse condition. The 270 brings in $27K! WTH? GT brings in a tad more? For an uber rare 270, you would think higher...
Hagerty also lists the 66 Barracuda higher $$ than the 65, now Im calling BS> 66 front end was...uh....er.....fugly. Yeah, I said it. Looked like a Falcon.
