The car's registration plate is "S2 TMR". In 1999, it appeared in Monte Carlo, Catalunya, Corsica, New Zealand and Australia, winning in Monte Carlo and New Zealand and gave Tommi Makinen his 4th world championship title at the final round in Australia. I think it actually became even more famous by being the car that's used by Tamiya, Kyosho and many other model makers, not to mention modelled in many computer games as well.
