You don't bother locking the doors because the driver's side and the rear hatch won't lock, and nobody will break in through the passenger side.
You don't care that you can't lock it because the PO wired the ignition to a push button and now nobody will know how to start it.
You don't want to roll the windows down all the way because you don't know if they'll come back up.
You've moved the door speakers to the dash so you can take the doors off in the summer.
Your friends, your family, and your girlfriend's family all know that when talking about your XJ they must refer to it as a Jeep, not a car, because you'll respond with a puzzled look and say "when did I get a car?"
You wake up and think "which electrical problem should I chase today?"
Nobody waves back.
You look forward to bad snowstorms because they're fun to drive in and you always come out of them with at least $150.
You leaned on your door and it caved in.
