After purchasing the Mini 4WD Starter Pack AR Speed Type (18706), I assembled it using only genuine Tamiya option parts. I have kept it in storage since then without ever running it. Although not pictured, I used Tamiya AO-1011 620 bearings for the axle bearings. I have not applied grease, so I recommend greasing it before running. The body (polycarbonate) was painted according to the instructions, but please consider it as a bonus as it was assembled by an amateur, including the application of stickers. Please check the images carefully before considering a purchase. I am also listing other Mini 4WD cars, so I would appreciate it if you would take a look. Shipping is done every night between 10 PM and 11 PM. If you have any questions, please feel free to ask.
