April 14th, 2016

If you’re old enough, you probably remember the cars from the late 70s and early 80s that weren’t good for much more than 120,000 miles before they started to develop real problems and were junkyard bound.

Here’s a quick rundown of some vehicles to consider which have a track record of being good for 250k miles or more:
