I remember Maisto's Fusion, and seeing it in a german toy store. I liked it, but its tyres were grey and chalky. Most large scale Maisto models had the same problem at that point, so I didn't dare buying it.

One day, I realized this was a chemical reaction with the rubber, and cleaning the tires with water and soap made them look alright. But I've never found a Maisto Fusion since then.
