Just looked into some data about where it's actually cheapest to buy cars across different states and honestly the differences are wild. Like, the average new car was hitting $48k+ back in 2023, but depending on where you live, you could end up paying thousands more or less just because of sales tax and dealer fees.

So I dug into what made some states way more affordable than others. The thing is, it's not just about car prices themselves. Oregon and Montana topped the list for being the cheapest state to buy cars mainly because they have zero sales tax. Oregon especially was interesting because even though dealer fees are super low there, the real win is no state sales tax at all. New Hampshire was similar - no sales tax, prices about 5% below average.

Alaska was kind of a wild card. Cars there cost like 20% more than the national average, but somehow it still ranked in the top four because dealer fees are literally the lowest in the country. Then you've got states like Delaware with no sales tax too, but higher dealer fees kept it from ranking higher.

The cheapest state to buy cars really comes down to this combination of three things: what the actual car prices are running, how much your state taxes you on the purchase, and what dealers charge in fees. Some states had high taxes but low prices, others had low taxes but higher fees. Wisconsin and Virginia were interesting because they had moderate taxes and reasonable dealer fees, so they still ranked pretty well even without zero sales tax.

If you're actually planning to buy soon, it's worth checking what your state's situation looks like. The difference between the most expensive and cheapest state to buy cars could literally be thousands of dollars, which is pretty significant when you're already dropping that kind of money on a vehicle.
