You hit 80,000 miles in what appears to be a ~20 year old GM (my '03 S10 has a similar gauge cluster with the same odometer/gear display) "a couple years ago?"
It was my grandfather's car for much of its life. He only ever really drove it like a mile at a time before he was no longer able to drive. When he passed away a few years ago, I got it. For being a car that survived Sandy and sitting in several feet of salt water, it has held up astoundingly well. At the time, all it needed was an electrical harness replacement. Since I got it, other than tires, brakes, and routine maintenance since, I've only just had to replace the exhaust line last year. It's been a damn good car, and I plan to keep it as long as I can!
I've got an '05 Buick Century with a similar story that just crossed 120,000 miles, and it's had a shockingly easy life. I put most of the miles on after my grandmother passed.
The similarity to my S10's gauge cluster, and the fact that there hasn't been an S10 with mileage that low since Obama took office, is what got my attention. I haven't seen that odometer display without the top digit lit in 15 years.
