Vintage Kyosho Optima Turbo

[Rcbro]

Hey guys,
I have a friend who has gotten ahold of a Kyosho Optima Turbo. Its in Fair condition and also has manual. On top of this he also has another roller that is missing a small amount of pieces.
The buggy has been sitting in his closet for months and he is now interested in selling it to fund his other rc vehicles. If someone could possibly give me a figure amount of what this may be worth or directed me towards someone who would know that would be great! Also does anyone have any idea on where the best place to sell it would be?
