Of course, some people like cars that are brand new. They may be interested in getting all the latest connectivity gadgets and other nonsense that people put in cars these days. If you don't need all this stuff, choose used cars! Most of the time, the good old fashioned way is the best way of doing things. If you're in a car, just focus on the driving - the communications can wait. Save money by avoiding all the excessive accessories that distract drivers and keep them from enjoying the drive, pure and simple.
Another reason that some people avoid used cars is that they're afraid they might not be fully functional. No matter how much others assure them that the cars are indeed quite functional, they still recoil from the thought of buying them. Hopefully, you understand cars well enough to know that a few years of use doesn't make a car worthless or dangerous. It just makes it cheaper, and it makes it a better deal for you.
So if you're looking for a new set of wheels, don't put too much stock in the word "new". Your dealership can point the way to a perfectly reliable vehicle that someone else has driven for a few years. Ultimately, you'll save money, and you'll get exactly what you need.
