If they let an SRT4 into the econo class then the SVT shouldn't have a problem, however I wouldn't be too surprised that even if I got into it to start, they might reclassify.
I'm sure the SRT got in there on some technical loop. The main thing they're supposed to base it on is the price of the car originally. Thought the base contour and neon are definite econo cars, the SRT and SVT were not.
