Saw some interesting data from 2023 about car buying costs and realized the cheapest state to buy a car varies way more than I expected. Turns out where you live can literally save or cost you thousands when you're shopping for wheels.

Oregon was ranking at the top for affordability back then - zero sales tax plus super low dealer fees around $353 made a huge difference. Montana came in second, also with no sales tax and fees under $600. New Hampshire was another no-tax state that made the list, though their dealer fees were a bit higher at $1,372.

What caught my attention though is how dealer fees can swing the whole equation. Alaska had car prices over 20% above national average, but because their dealer fees were literally the cheapest in the country at $315, it still ranked in the top 4 for overall affordability. Kind of wild how that works.

On the flip side, places like North Carolina and New Mexico had higher sales taxes but kept costs reasonable through lower dealer fees and moderate car prices. Wisconsin made the cut too despite having the highest dealer fees in the top 10 - their car prices were only 1.3% above average so it balanced out.

If you're actually in the market, the cheapest state to buy a car really depends on the combo of sales tax, dealer fees, and what the baseline price is in that area. Delaware with zero sales tax but high dealer fees ranked 5th, while states with moderate taxes but rock-bottom fees sometimes did better overall. Pretty wild that your zip code could literally impact your car purchase by thousands.
