Should you purchase a car that's older than 15 years even with low mileage?

I would buy one thats 25 years and older...

A lot of technology today is not really all that great. The car decides for you what you can or can't do. - example - Most all wheel drive cars decide if and when they are going to give you traction or not. That mechanical full time systems are superior is proof that technology does not always make things better. Not to mention that all these "smart" systems are destined to fail and are difficult and expensive to diagnose and repair. Most tech these days takes control out of your hands and a lot of the unnecessary complications are to add a tiny bit of economy which ends up costing more in the long run due to electronic failures.

People driving around in cars with malfunctioning electronic systems that are too complicated and expensive to repair is less safe, not more safe. I will take an old car in good shape any day over a lot of cars today.
