You don't say what maintenance had been done prior to this trip.
If it's a "new" car for you, I'd certainly go through it, one end to the other.
Change all fluids, filters (gas, oil, air, brake fluid, transmission, rear end.)
Check brakes, shoes, pads,drums, discs.
Check all fuses, bulbs, accessories.
Check hoses, water levels (overflow tank, windshield wiper tank).
Check plugs and plug wires. (Good way to do this is when it's really dark , Open the hood and have someone rev the engine up. Look and listen for arcing of the electrical spark each wire gets. If you hear or see one, replace all the wires, not just that one)
Most cars don't start giving owners problems until over 80,000 miles or so. But a good preventative maintenance program can certainly extend the life of any vehicle.
Our 1988 Ford Bronco II (bought in 1987) I sold recently had 296,000 miles on it. Ran great, new owner drove it off my yard.
That's just one example.
IMHO, doings little things now prevents a lot of bigger things down the road later.
