I will always go with a 72 and earlier car. I hate the plastic in the later ones, the small inside door handles, and most everything but the beaker does n ot bother me. Would I buy and build a beaker? Yes. But it would have to be a solid project, complete and priced FAIR>>>> Haven't seen such ion 5-6 years!
Like Al said, $ would better be spent on a good and real muscle variety IF you could find a good candidate and not priced by a dude on really bad dope! But, we generally build what we have and like.
