Now that SUVs have become more expensive, small compact cars are in demand.  Mazda3 is an example. CoPilot Price Pulse estimates that the average price of a 2009 sedan is $7,665, with a market premium of 43% (compared to normal market conditions). Newer models still command higher prices than older models. Mazda3 sedans sell for $23,510, a 26% increase over last year's price.
