I have a collection from the bankrupt Vidámpark of Budapest:
A car from the dark ride named Tréfás Dzsungel (Earlier: Szellemvasút)
and a Italian bumper car.
I want to make both cars work again.
I already have a few parts for the dark ride car and it's chassis is being re-manufactured right now.
The bumper car is more of a challenge, since I have no spare parts for it and ordering everything for it isn't cheap.
(I was lucky enough to get a few parts of the dark ride car from the original seller, but sadly, I was late with the question about the bumper car's parts and he threw everything he had away.)
