I agree its very hard to cut through the noise surrounding prices. Hemmings is asking prices, so I would say no, but if you watch it for several months, along with other resources, you will start to get a feel for the prices.
I looked up the white KR and it looks very nice. But, you would have to know some of the history of the car before you can make a determination if it was a good buy. I dont know the history.
I can probably find you a car that has multiple national championships for that price.
The auctions are a great resource, sometimes good, sometimes not so good.
I have been watching 1968s for a long time.
There are always blips...but here is a another resource for you...
