Nope, this is exactly what I say : TA 04 and 414 are different cars, whereas T1 Evo 2 and T1R are the same cars, just a cheap version and a HQ version, like the TC3 racer is for the TC3 FT.
But there is not any DIFFERENT cars that are such similar, is this so hard to understand what I say ? Sorry for english not being my mother's tongue langage.
