This model was very fun. Like other Tamiya models, fitment and instructions were very good

I've built two of these kits in Martini Racing and in Jaegermeister team colors and they are very accurate even though the kit is around 40 years old. The fit is very good and the color callouts match most references I've found on the web and books. The bodyshell is cleanly molded with some mold parting lines on the front and rear quarters and the engine cover/lower rear spoiler is molded in one piece with openings for the intake grille and mounts for the upper airfoil. The engine and transaxle are nicely done given the age of this kit but adding some hoses, wires and linkages would really make it shine. The decals on both versions went on easily and with a few dabs of Micro-Sol they settled right in. At 1/20th scale they are bit larger than the norm but there are kits by other makers in the same scale as well as some other Tamiya kits. I would recommend that you have built a few kits before tackling these since there is a fair amount of painting to be done and they do require following the instructions exactly to ensure that famous Tamiya fit.
