I used to have many vintage and re-pop tin clockwork cars from Schuco, Distler and Marklin.
Varied in scale but the old Distlers with 3 gear range forward selection and one reverse trans were my faves.
For size and weight, the 1:12 scale, chrome Marklin 300SL is terrific. Irresistible to kids of all ages. To handle it and wind with the big key, let race across a room is a hoot. The open red Benz is also in large scale. I forget but maybe it was Schuco sets that came with the wrench kits. They had 'knock-off' wheel hubs and tiny mallet and rear jack.
Much prefer the early originals but the re-pops are super neat. Some of the Marklin depicted.
These two are large scale wind-up. Battery powered headlamps.
