I kept my old car until I couldn’t stand it and inspections were coming up with costly repairs needed. The ac stopped working, I was playing music through an amfm transmitter. It worked alright otherwise. New car (was pre owned but certified) has Bluetooth to connect my phone, drives better, has working ac again and some nice safety features. I’m hoping I can keep the car going for 10 or more years until I need to find a replacement again. I suspect next car will not be as drastic an improvement unless catastrophic things happen with my current car.
