Yup. The Czech one would be a nightmare to polish up. Get through gallons of shoe wax polish and wear out many, many brushes. Would LOVE to see one in a patent leather though. ?
Interesting fact, discovered while looking into subject of cars for disabled, the USA seems to have made none. Except one or two 20s things which were like push-bike trikes with a single-pot ICE glued on. Most of the US efforts seem to have been adapting existing cars for the purpose. Guess they were, relatively, so cheap in the States that it wasn’t worth gearing up for a specialist model?
