If you just bought the car, you have an idea of a fair price. But there is no way to judge condition or value without a full set of very good photos.

Sprints ARE rare. That doesn't mean they currently fetch exceptional pricing. But just because the $$ are not yet there does not make them less worthy.

Some will say yank the Sprint and put in a V8. Others will say keep it stock. It's your car...but I really enjoyed owning and driving my Sprint Le Mans (drove it to Detroit from northern Wisconsin, and all over Michigan) and it got great mileage and attracted a lot of attention because it was different.

That car was too pristine to modify, and I eventually sold it to a collector with no intention of altering it. It had the 2 speed trans, and needed a 3 or 4 speed to perk it up off the line. I couldn't bring myself to modify a 37,000 mile car.
