Suburban is now "mature"

When we talk about people we don't like to say their getting "old".  So we talk about our "mature" population.  I guess the same can be said for cars, right?  So our suburban is now officially "mature".  Today we hit 200,000 miles!  Now, for complete disclosure, we didn't drive all 200,000.  We inherited many of those miles when we bought the truck.  But we were there as a family when the odometer rolled over!
