Just looked into where it actually makes sense to buy a car in different states and the differences are wild. Turns out sales tax and dealer fees can add thousands to your purchase depending on where you live. I found some data from a while back that breaks down the cheapest state to buy a car, and it's not what most people think. Oregon comes out on top because they don't charge sales tax on vehicle purchases and their dealer fees are super low. Montana's another interesting one - no sales tax there either, plus they keep dealer fees minimal, even though car prices themselves run pretty high. New Hampshire also has zero sales tax and lower-than-average pricing overall. What surprised me most is that Alaska ranks high for affordability even though cars cost over 20 percent more there than the national average. The reason? Their dealer fees are basically nothing compared to everywhere else. States like Hawaii, Delaware, Virginia, and Wisconsin also made the list because they balance reasonable car prices with lower fees or tax advantages. North Carolina and New Mexico round out the top 10 even with higher sales taxes because dealer fees are kept reasonable. The takeaway is that where you buy matters almost as much as what you buy. If you're shopping for the cheapest state to buy a car, looking at the total package of sales tax, dealer fees, and base prices makes a huge difference. Could save you thousands if you're willing to shop strategically.
