That's not really the usual concept of "inflation". Every commodity fluctuates in price. Inflation is when the price of a unit of money falls. Conceptually, it's very easy to distinguish "cars cost more dollars because cars are more expensive" from "cars cost more dollars because dollars are cheaper". In practice, it's difficult to measure the value of a dollar. But in general, inflation looks more like the price of everything going up, and less like the price of cars going up.

(Currently, a lot of different prices are going up, and current inflation is high. But you can't just point to Toyota raising prices and say "See? This is what inflation looks like!" That is what inflation looks like, but it's also what not-inflation looks like.)
