Another little known cottage industry in Germany produced this interesting 1/24-scale kit in 1969, partly inspired by the Russkit offerings from America, very popular in Germany between 1966 and 1968, and almost a straight copy of the other Russkit inspired, Italian Unicar chassis. In any case, quite scarce and they apparently issued quite a few models according to their in-box adverts...

A later angle-winder version of the chassis appears to have been produced...
No use to tell you that just as the Unicar models do, the Monza cars, powered by the latest mabuchi FT16D with can ball bearing, would clean the clock of a Russkit "Carrera Series" assembled kit.
But one German car would beat both: the 1/24-scale Fleishmann Lotus 40, possibly the best RTR slot car kit produced in the Classic Era:
