-it was discont'd long ago., even when new, it was around $100. I don't think they'll go up in value, unless NIB, & about 5-10yrs. down the road. Is this what you mean?
-I have the H2 4x4x4 Hummer, & 2 of the F-350 Mattracks trucks, (same platform), they're a decent truck for the money. I don't know where to get parts, since I'm not sure who actually makes them. They're not Nikko, but it could be companies most of us never heard of. I think Nikko quit selling in the USA anyway, they had to recall a product line-up of 1/10th vehicles that caught fire.
-I'm sorry to waste time yammering, are you needing a price idea to sell a MP, or to buy one?
