Our daily commuter (carpooling as of this week!) is a 2003 Kia Rio with 240,000 miles.
We have multiple vehicles as well. Running are the Kia, a 97 Jeep Wrangler with ~159k miles and our backup, an 81 Toyota Tercel which is over 150k but under 200k, I think.
The Tercel gets the best fuel mileage, but no heat, no AC, and a passenger seat which won't sit up straight make it uncomfortable for carpooling long distances. However, it would get us there in a pinch, which is the reason we have a backup. It costs us $21 and change in registration and tax annually plus under $100 in insurance- cheaper than having to rent a car for three days, in other words, and that without factoring in the 45 miles to a rental place.
The Wrangler does mostly off-road, not as in recreation but as in getting to places that don't have pavement (like our house, though the cars will get here if it hasn't been storming badly).
