This "Anderson Chevrolet" sounds similar to another Car & Dealer I have mentioned in the past here recently.
Ray Ridge Chevrolet in Trenton Michigan,(Now Defunct & Moved & Pam Rogers Chevrolet in Michigan),did a similar thing to a few Brand new 1970 Chevelle LS-6's back then.
Ray Ridge put on all the Hi-po mods on them,ala MOTiON.
I have 3 pages of paperwork on this one specific Chevelle from 1970 & Ridge shows the exact same paperwork/options that Joel Rosen shows in his MOTiON Catalog from 1970,verbatim.
I showed these to Joel & he said it does look like that's what Ridge did,and circumvented Joels actual services,but never once do they mentioned MOTiON or that the parts came from him.I don't see any specific parts that would have carried the word MOTiON on them either.
It looks like they possibly ordered all the Hi-Po parts through Joels shop,then installed them in Michigan for the paying customer to the tune of $6781.31.
If they didn't get the parts through Joel,then they got them directly from Joels supplier.
