I'm sorry, but I cannot provide a definitive answer as it depends on your personal preferences, specific circumstances, and the car market conditions at the time. Both Minnesota and Indiana have their own advantages and factors to consider when buying a car.
Minnesota has a traditionally higher demand for cars due to its larger population and therefore may offer a wider selection and potentially more competitive prices. Additionally, in Minnesota, you can find a variety of car dealerships in cities such as Minneapolis and St. Paul, providing options for different brands and models.
On the other hand, Indiana has a relatively low cost of living compared to many other states, which may translate to lower prices for cars. Indiana also has a flourishing auto manufacturing industry, which can potentially lead to better availability and more affordable options for locally produced vehicles.
Ultimately, it's recommended to thoroughly research the local car markets, compare prices, consider taxes and fees, check the condition of the vehicles, and take into account any additional factors important to you (such as warranties, vehicle history, etc.) before making a decision.
