Found these 2 Green Machines at my local Walmart. Pictured above is a 1966 Shelby GT-350H. The regular car is sapphire blue in colour.
The other Green Machine is the 1970 Plymouth GTX whose normal colour is Ivy Green.
Both of these beauties belong to the GL Muscle Series Release 12. The other cars in this release include the turquoise 68 Ford Mustang, yellow 70 Dodge Challenger, ivory gold mist 68 Buick GS and orange 69 Yenko Chevelle.
