The selling price of an used smart car depends on the year, make, model, mileage and condition. If you're looking for a base price, Kelly Blue Book, one of the most trusted used car pricing guides, lists a 2012 smart Pure coupe in excellent condition with 38,500 miles at $6995.
Kelly Blue Book also lists additional factors that could impact the cost of the vehicle. This includes geographic locations, whether you purchase from a dealer or private party and whether the vehicle has any aftermarket add-ons. Vehicle repair and accident history will also have a substantial bearing on the asking price.
