No, it's not the same concept at all. When I go racing I'm in control, i'm doing the driving and having fun etc. With all of these animations I press a button and watch an animation of someone painting my car or changing my oil (magically, I might add on that one). That's not fun, I don't sit having fun watching an animation over and over and over again. I mean do you want animations of someone fitting your parts as well? How about an animation for changing your tyres, with wheel balancing as well? Like I said, it's pointless fluff in my opinion.
Also you say it takes ten seconds, what if I paint 500 cars? That's 83 minutes of gaming time wasted just watching cars being painted.
