I'm driving a 27-year-old Lexus with over 300,000 km on the odometer. My son's BMW is also about that range. Neither of us are even thinking about getting newer cars at this point, and we regularly drive them halfway across the country without any concerns about reliability. We do keep up regular maintenance, and the brands are generally viewed positively.
One thing that may help is that cars are designed and engineered such that they very very very rarely just simply stop working. The only thing I can think of in that vein is if the timing belt or timing chain breaks. In the case of your car, it has a timing chain and an interference engine, which means engine damage if it ever breaks. So you might want to stay on top of that particular maintenance item.
Other than that, cars are generally made such that breakdowns happen gradually rather than suddenly. So an older car might start leaking oil, or the brakes might feel a bit mushy, or the steering is a little loose, or the car takes a couple of tries to get started, or the air conditioning is no longer 100% ice cold freezing. These gradual failures are such that you'll usually be able to notice them and at least get the car to the nearest service station, or, vastly more likely, get it fixed at your regular mechanic sometime in the next several weeks.
Some things on less critical parts of the car can fail suddenly. If a window regulator goes out, then all of a sudden you can't roll the window up or down, but the car is drive-able.
Also, nowadays, with cell phones, even if you were stuck on the side of the road (which again, is extremely unlikely to happen) you can almost always call a tow truck with your cell phone and they'll get your car to the nearest shop.
(I agree with Frankies Girl's advice also.)
