What is the maximum # of used cars per family that is viable too keep running?
My family relies entirely on four, all with miles over 150K. Its very economical, but a bit tiring. Not one is ill-maintained and everyone works like a charm. We even use these for road trips and vacations.

The only problem is, sometimes it gets a bit tiring. It gets a little demoralizing going too junkyards when others are going golfing...I mean I had tires to rotate this weekend, but all I did was nap. You can only burn the midnight oil so much and Mother Nature catches up with you...
