Product Description
2021 Hot Wheels Rocket Oil Special Purple Art Cars 9/10 #158 GRY37 Metal Base
Add a colorful piece of Hot Wheels land-speed-inspired history to your collection with this 2021 Hot Wheels Rocket Oil Special, finished in striking Metalflake Purple.
Released as #9/10 in the HW Art Cars Series and Collector #158/250, this unique fantasy racer features bright orange and yellow paint-splatter graphics along with the special HW Art Cars heart/logo design.
 
The purple body is paired with an eye-catching mismatched wheel combination featuring an Orange AeroDisc front wheel and Yellow AeroDisc rear wheel, giving the vehicle the distinctive artistic appearance associated with the HW Art Cars series.
 
The Rocket Oil Special takes inspiration from early land-speed-record racing machines, featuring a long streamlined body and exposed V16-style engine design.
 
Mattel product number GRY37 identifies this exact Purple 2021 Mainline variation.
One particularly interesting feature of this release is its metal body and metal base construction, something increasingly uncommon among modern basic Hot Wheels Mainlines.
 
The car is New in package: See pictures for quality and variations. The card may have some shelf wear on corner and edge.
