yokomo advice

[racingdwarf]

I have been offered a car by a racing friend who I think bought it in a job load of vintage tamiya as thats more his thing. I'm not sure what it is, to me it looks very 870c based. He has looked into it and thinks its a yokomo hotdog 4 and quite rare.Its rough but clean, stick pack chassis, no shocks

Im after some advice on what it is, what I should offer for it as I don't want to steel it from him, I will pay what its worth......but I have no Idea what its worth so I'm in need of some yokomo expert advice

I'm trying to post pictures but with no luck at the min, the upload screen just goes blank
