Example of what "driver" Barracudas are selling for

Interesting thread here. This really got me thinking about prices in my neck of the woods out here in the northeast, specifically CT. Obviously there is a premium paid for rust free cars here out east. In my opinion there are a lot of variables when asking what is a driver barracuda worth assuming we're talking 2nd generation 67-69. It isn't an easy question to answer. Examples in my opinion of some variables assuming all nicely presenting drivers nice 3+ cond. fully functioning.
1. 67-69 fastback/notchback 318 or slanty w/auto trans approx 10,000.
2. 67-69 fastback/notchback 340 4 speed car 15,000-18,000.
3. 67-69 same car w/matching #'s. 20,000-24,000.
4. Same as # 3 but conv 28,000-32,000
5. 67-69 fastback/notchback clone 383 4 speed car 23,000-25,000
6. 67-69 same as # 5 but legit w/matching numbers 30,000-33,000.
7. 67-69 383 4 speed conv w/matching numbers 38,000-42,000.
I'd like to know based on the present mkt for a bodies what does everyone think? Am I realistic or way off? I realize that 68 or 69 very often brings slightly more than 67. Also color choices make a difference.

By the way MrJLR that barracuda looks nicer than a respectable driver. Well bought!
