How much will my car depreciate in 5 years

Depends on the vehicle. 80% or higher.

If you don't maintain it, beat the tar out of it, and put a lot of miles on it then it'll be worth very little. BTWs value typically takes a nose dive as they approach the 100,000 mark. People familiar with them know that's when they start falling apart. Look at what 2018 models are going for to give you an idea. They're six years old now which is how old your '23 model will be in five years. Jim
