Sadly even old computers will being to break at some point. My Ford Focus is old enough to drink too and the central unit has become flaky, like numbers disappearing from the odometer and the speedometer going to 0 in mid route. The repair shop said those were dirty contacts, then the soldering, then they took it to a 3rd party... they didn't solve anything. The mechanics of the car are still good, but I feel like its time has come because now I'm not feeling confident of taking it for a long trip.
