I have a Kyosho Sandmaster MKII hat I would rate as an 8, or 8.5/10.
It has the original Kyosho engine, which feels good, and original wheels/tires, and body.
The body is a big rough, but underneath, it is in spectacular shape.
The clutch is brand new, and from Traxxas (because when I got it, it didn't have a clutch), and the servo mounts are Tamiya, other than that it is all original.
Let me know if you are interested, and I can send pics, too.
