my neighbor, who has coveted my challenger from day one, has finally got the green light from his wife to buy a challenger. he has found a 2010 srt8. when he went to go look at it at the used car lot, he found that he couldn't rev the engine after the first rev. he pressed the throttle and the car didn't rev. salesperson said it was a feature to keep the engine safe from over revving. I think I had heard something like that when the srt8 was introduced that year, but I may be wrong. he said the car runs and drives like a top, except for when he wants to rev the engine in neutral. car has 46k miles and the Carfax has one accident, rear passenger quarter panel, no frame damage. thoughts?
