When I buy a car I like and find out it has no engine, like my R34, it kills me a little inside to see that tamiya doesn't have enough nuts to make all their models with engines. Buying curbside is okay for lowriders with working motors and such, but seriously, why waste time producing models without motors? Tamiya should put motors in all their models, and I bet their purchase rate would rise, not just tamiya, but fujimi, revell, aoshima and all the others. We need more engines!
