Iowa is one of the most expensive states to purchase a used car, according to a new analysis of sales data from used car marketplace AutoList.com.

The company's study analyzed more than 81 million vehicles and 4.6 billion unique data points nationwide. Iowa ranked as the 34th most affordable state for purchasing used cars.

Maine came in at No. 33, with Tennessee finishing just below Iowa at No. 35. Florida was the cheapest state for purchasing used rides, the analysis found, and Wyoming was the most expensive.

On average, a used car in Iowa is $451 more expensive than in other states, AutoList found. Things are even worse in Des Moines: prices in Iowa's capital city are $795 more than in other U.S. cities. Des Moines ranks as the country's 795th most affordable city to buy a used car or truck.

Using the available county data, AutoList found five counties with the cheapest used car prices: Jackson, Calhoun, Jefferson, Wapello and Hardin, in that order.

Davenport is the best Iowa city to purchase a car: Prices are $219 below the state average. The next four best cities to buy are Cedar Rapids, West Des Moines, Des Moines and Dubuque, the study found.

AutoList's analysis also found the best deals to be had in Iowa. Five models — the Chevrolet Corvette, Ford F-350 Super Duty, GMC Sierra 2500HD, Hyundai Santa Fe and Ford Expedition — can be purchased here for an average savings between $604 and $1,177, when compared to national averages.

U.S. car lots are poised to be flooded with used cars coming in from expired leases, USA Today reported in June. Prices could decline by as much as 6 percent in 2017 and by 3 to 5 percent in 2018, according to LMC Automotive, a marketing data firm.
