Would this scare you guys off? I'm about to purchase a 2009 C6Z and noticed is has NT05 tires on it. The car only has 7k miles. This worries me that the car has been tracked or abused. But it is pristine inside and out. What do you folks think of this? Maybe (I pray) the previous one owner just didn't like the stock tires? Maybe too loud or something? Help!
