Advice on 67 Barracuda Convertible

Hello everyone...new guy here. Sorry if this is the incorrect place to post some questions, but I need to act quick on this car...

It's a 1967 Barracuda Convertible V8 273 4BB Commando. Auto. Red with White Top and Leather interior. Has A/C and 40k original miles on it. Car is in quite good shape. I know there were only 4,228 convertibles made in 67. Is there a way to find out specific production numbers on it.. I did pull the vin and ran the report on where is was made, confirmed engine, etc...Not sure if it's considered rare or not. any thoughts? The current owner is asking $8,500 What are your thoughts on price?

Any assistance would be greatly appreciated. .

Sincerely,
