Russ,
I have been looking at replicas recently. The yellow car is a repaint and I believe has some accident history as well. The black car was listed as a 'Beck', but an eBayer complained that it is not and they admitted that and edited the listing. You might want to be very careful with these guys, they knew it wasn't a Beck car but cut and pasted copyrighted material off the Beck website.
YMMV ;)
