That’s an increase of about 8% per year, in round numbers, since you bought the truck.
We would need a cost accounting, to see the breakdown of costs which make up the price of a car.
Have labor costs gone up? Prices of component parts which go into cars? Have pension and health insurance costs for employees risen? Rent for the car lots, costs of operations of car dealerships being passed on to consumers?
Have they marked up the sticker price but will be flexible on the price when you are in the salesman’s office?
If I could buy a 2019 vehicle with the EXACT SAME standard and optional features as the 2006 vehicle, it would probably cost LESS!
Since there’s no ability for the manufacturer to use shrinkage to keep their price competitive that’s a nice measurement of inflation for an American made product.
