If you can find a car that is 6-12 months old, sure. Assuming it wasn’t a rental in a previous life. Or a lemon returned by its previous owner due to massive issues.
Most people who buy new cars keep them for a relatively long time. And during that time they require minimal maintenance.
The “biggest decrease of value” assumes that, to you, the value of the car is determined by what you could sell it for. But that’s not the case. To you, the value of the car is what you spent on it. You then amortize that value of the car over the years you operate it. The only person who can tell you whether you got out of a car what you paid for it is you.
