I couldn't agree more. About 2 years ago before I got my xr6 turbo I did quiet a few test drives. A couple were an XR8 and an XR6 Turbo ex cop cars , same age as the one I ended up buying and similar Km of around 50,000km. however the ex-cop cars were a mess. The entire dash rattled at the first sign of a pot hole. The V8's rotors had visible cracking indicating very hard braking regularly, when I pointed that out to the sales guy he offered to replace them but I declined buying it because it just showed how much that car had been thrashed and how hard a life it had lived. That car was around 3K cheaper than the non cop car, but for the sake of a few grand it was far safer to get a non cop car that hadn't be pushed to its maximum limits most of its life. I couldn't tell about the engine but its a fairly good assumption that it was stressed a lot more than a family owned xr6 turbo car would have been. Think about it how many times can a regular road user push that hard and not lose their license? And 2 years later I have had no issues yet with the regular family owned 2nd hand xr6 turbo that I bought. (touch wood)
