Anyone who has actually seen both a WRC car and the car on which it was based, in person, knows there is a huge difference between the two. Your car is nice, but it won't do 0-60 in 4 seconds, and it won't jump 5' dirt hills at 100mph and keep going like nothing ever happened. That's OK because you couldn't afford the WRC car. Not only are the shocks on a car like this $3000 per wheel, but they require a full time engineer from Penske or Ohlins or whoever to be on site just to tell you how to adjust them. Also, the anti-lag systems on WRC cars are louder than bombs and shoot fire from the exhaust, they are very hard to drive slow, and the road noise is fierce since there is no carpet or padding.
In the Group B era, where there were "evolution" versions of rally cars (technically) for sale you could, kind of, made the case that the road car and the competition version were similar, but not with something like this. The only overlapping parts are the shell and the block, maybe the suspension uprights, and the lights...maybe the blinker knob. However the head, the turbo, the ECU, all the manifolds, the control arms, springs, shocks, bushings, the entire brake system, all of the transmission and diffs (maybe not the case, but certainly the guts) and prop shafts, and all of the interior are either HEAVILY reworked or thrown out completely. And since this was the last Toyota WRC car (due to them being banned for cheating) there may have been even more than that done to it.
If its 'good enough for you', that's fine, that's what the Toyota marketing people want you to think. That's why they go racing in the first place, to sell cars, but...its all bullshit.
