Have you ever heard of a car going 500,000 miles before? How about doing it on the original engine and transmission? If you have, it's likely that it was a boring 4-cylinder economy car. That's all well and good, but we think if you're going to choose a car to drive half a million miles in, it might as well be one with a V8 and some style. David Mayans, of Corona, California, agrees with this sentiment, and that's why his '87 Camaro IROC-Z currently has a staggering 416,000 original miles on the clock. That's nearly the distance to the moon and back! Plus, by the time you're reading this, the car's odometer will read even higher. David daily-drives the IROC, so its mileage grows closer to the 500,000 mark with each passing day.
