FWIW on the red car, that seller (jimr231) was the same one that listed the Alpine with Tiger sheetmetal that I ended up buying later (not on ebay). He was actually listing it for someone else who isn't very computer savvy. When I went down there to look at the car I was quite surprised to see his "collection", which includes probably 5 or more MKII's. He was just finishing up a MKII restoration for a customer that looked great, and had just bought the MKII that was featured on "Counting Cars"-- when he saw it on TV he hunted it down and bought it. The same seller also just sold a few high dollar parts-- a tool roll, NOS chrome MKII headlight rims, a NOS MKII owners manual.
I can't vouch for anything, but this certainly isn't a fly-by-night flipper.
