My wife and I have a 1999 Camry that we inherited from her grandma. It somehow only has 130k miles on it and a mechanic said it’s in great condition and may run for another decade.

We’re trying to invest some money into it to give it some modern amenities. We were looking at adding CarPlay and maybe a back up camera.

What do you feel is worth the cost and reliable enough to add to a car that old?
