I think the most beautifull CART cars where around 1997 to 2000 (Reynard and Lola chassi, Swift chassi was damn ugly and slow :P), after 2000 the cars had minor changes but were still fine. But this shape dosen't look like a top series car, it look's like more a Jr. serie car.
In fact the car itself looks better than the drawn I saw last year, but it still not give me the feeling for a top serie Car.
Also I hope IRL and CART merge soon, so we have again more than 30 cars on the series...
