your car is VERY nice - AND at $9600, i think you got an EXCELLENT deal!! i think you could easily get $15-18k out of your car the way it sits assuming the interior and drive train are as nice as the body.
your car is a very good benchmark for guys on FABO trying to buy or sell a 67-69 barracuda - either a parts car or a nice driver.
the deal you got shows that there are good buys out there for muscle cars and that the cars that are advertised for really inflated prices should not be taken seriously.
