The short-lived Solstice is unforgettable, and in case you are looking to buy one, you're not alone. It is one of the most affordable collector-spec cars sold in recent years, with the potential to appreciate over time. We all wish the stars align for us the way they did for the Pontiac Solstice in its four years of production. GM’s Pontiac introduced the Solstice as a concept car at the 2004 North American International Motor Show.
