That depends. If someone is asking a reasonable amount, it will sell for the asking price. What do you consider "on the high side"?
Describe the cars and features you are looking for and I am sure you can get opinions on the value. But keep in mind, we all have "opinions" and what someone thinks is a value, others might think it is over or under priced. Often, it is very subjective.
Example:
In my "opinion", the company selling the SPF in Washington for $70K (small block with EFI) is on the high-side.

By comparison, The SPF 1000 that is for sale on this site appears to be a good value at an asking price of $44,900 (396 with hardtop)

Give us exactly what you are looking for and what you expect to pay for it and maybe someone here can post a lead for you.
Good Luck.
