I agree with Marlin. Go with your heart. If having this car will make you happy...go for it. If you're solely lookng for an investment...look elsewhere.
I don't see a lot of Cougars at the shows I frequent in AZ. If you buy the car...you will definitely get a LOT of looks with it.
If you buy it...drive it! There's nothing better than a drive in a cool car to relax you.
