The best and most famous of the Japanese slot car kits manufacturers, Tamiya is now the world's largest model kit manufacturer. Their slot car racing kits are well known, but few are aware of their very limited production of RTR cars. Tamiya kits and parts are pricey in every form, from mint to used, showing the high esteem in which collectors hail them. Tamiya sold kits, RTR and body kits as well as virtually every part from their kits. As with most Japanese kits, while they were designed to fit the Mabuchi motors, the motors were not supplied. Tamiya's last slot car kit was issued in 1968.
