Last month a guy showed his GT/CS 390-4V on the site. The cursory photos made it appeare to be in GOOD condition at best. Based on the options in the list, this car would have valued at about $12K. I do not remember if it was a GT or not, but for discussion sake I assumed it was. Many said the car was worth $15K or maybe more. I understand the list is VERY limited with the big block info, and I understand the emotion that goes with the purchase, I am just curious as to the descrepancy and any thoughts. [/quote]
Bryce,
Yes, the $15k valuation given by me was actually based on the car being in "Excellent" condition with a little fat thrown in because of the known history. I used the Excellent category due to the 2nd place finish at Knott's, assuming that the pictures that were posted didn't do the car justice. If the car is in fact in "Good" condition, then you are correct about the price in the guide being around $12k according to the guide. It's hard to tell from the pictures what is wear and tear and what is just dirt and dust from sitting. Either way, the guide may be way off for this car. As you pointed out, data here is almost non-existant.
I believe that my guide is very accurate for 289-302 cars, which made up most of the data. There were a few I6's in several conditions which fit in nicely into the data I already had. The values for the 390's, however, are just my attempt at applying the Mustang Monthly data to the GT/CS. As for the 428 cars (Doug), I think it's really name-your-price.
The purpose of this price guide is to give a reasonably accurate average value for things based on actual transactions so that people can conduct their own transactions in confidence. When there are few transactions, you can use a little estimation to fill in the blanks, but some of the confidence is lost. When there are no transactions, there is no ability to assign value. I don't want this to be one of those guides that dictates price and influences the market, but rather one that "receives" prices and is influenced by the market. I would like the market to be what it will, and for the price guide to follow.
