I have a 2018 EX with 115k miles. I’ve spent quite a bit on tires and oil changes, air filters, and a set of front brake pads, plus a new battery. I add some fuel system cleaner to the tank occasionally. Gas cars are still costly to maintain and aren’t as fun with their MPG.
Do you know if the VIN starts with a J? If it does, then it’s a good choice.
Try not to stress about what might go wrong. Overthinking these forums can lead to unnecessary worry. All cars can have issues, but you can increase the chance of getting a good one by keeping up with maintenance and not driving carelessly. Fits are generally reliable cars that don’t require much care, so just enjoy the ride.
