I know of a guy in the states that paid over $80000 (80k) for a hot wheels Vw surf bus, it was a prototype only, and never made full production because it was too narrow, and wouldn't work on the launcher that sent other cars down the track! The later version that went into production had surf boards mounted on the sides, that made it wide enough to be used in the track launcher
I'll get my anorak
