This is an great find! It's the Porsche Boxster from Racing Champions Concepts and Muscle series. This was produced over 10 years ago. It's been at least a decade since we've had one in stock, as they were immediate sellouts! 

Now we know the Boxster was a production car, not a concept; and its closer to a chick car than it is to a Muscle Car, but somehow it ended up as part of RC's Concpets and Muscles collection. That being said, this is one of the more nicely detailed casting of the Boxster that we've ever seen. If you collect Porsche, Boxsters  or Racing Champions this is a great find for your collection.
