This is the 40 Somethin' from Hot Wheels. According to the HW designed that created it, Eric Tscherne, it's inspired by the Ford GT 40. It was also released when the Fords GT40 "reimagine" was released in 2002. 

We don't see the resemblance to a GT 40 from the front, but can see it from the rear view. 

This color was released 15+ years ago in 2007, and it's the first time we've had this particular color in stock. If you collect HW Designed vehicles or Hot Wheels this is a wonderful addition to your collection. (1:64 Scale)
