This has likely happened to you a few times in life: you see a cop car in your rearview mirror, instinctively check your speedometer, and hit the brakes -- only to realize, oh, it's just some quirky civilian who has procured an old cop car for God knows what reason. Weird.
Here's the deal: an ex-cop car can be a great daily driver for many reasons -- beyond just scaring the shit out of texters and encouraging other cars to stay out of your way. They can be amazingly comfortable and fun to drive, thanks to the heavy-duty "police package" that makes them powerful enough for a high-speed chase. Plus, they're cheap to maintain and durable as hell.
That being said, some ex-cop cars are used, abused, and worth more in pieces than whole. Others have received the crème de la crème of care and upkeep. So how do you know when you've got a winner? Here's where to look and what to look for.
