I'm sure some build and then want to sell because they accomplished what they set out to do. Build it.
From a perspective of someone that is not a builder my read on it is that most sell because they "think they wanted a Cobra" because of it's iconic status and performance. Many who buy are not really into Shelby's or the history of the Cobra, Carroll Shelby and Shelby American i.e. not true Cobrafiles/Shelby fans.
They buy the car, find out it is hot, uncomfortable, loud, smells of exhaust, requires regular mechanical attention, wife/girlfriend doesn't like it and it's a 1/2 hr to 1 hour car at best before most want to stop and get out.
In short it's not in their blood and they would now rather sell and buy something more civilized and practical with great performance such as Z06, Viper etc.... In most cases it's alot of money to have tied up on a car with limited use, practicality and narrow marketabilty.
I have owned my Shelby for 12 years now. She's officially an old girl. It's half way to being a "antique" in N.J. as far as license plates are concerned.
It's still loud, raw, hot, smells of exhuast and it's always "something". My wife still hates it. I'm am now in the process of rebuilding both carbs and constantly tinkering..but.. I still love it as much as the day it arrived from Shelby. I guess it's in my blood.
