when you hear a new strange noise from under the hood,wonder if the engine will quit, and if you will be left stranded. Several minutes later it stops, you question why, wonder if the engine will quit, and if you will be left stranded.
when you weld parts together instead of screwing them just so they will finally not come loose knowing full well you will have to cut them apart in the future to make other repairs.
when you're afraid to hit bumps, not because of loosing parts, but because the new quick catching seat belts pull a death-grip bear hug on you and you can't breath.
when you love to hear that someone needs a couple of things from the store and volunteer to go because it's an excuse to drive the CJ.
