The Suzuki Aerio seems to have no power and no leg room. The engine size needs to be a 2.8 liter or larger. This will give much better gas mileage and power to pick up speed due to the wieght of the vehicle. The steering wheel needs to be raised more up words. The dash board could have more features. GPS maybe. This is a family station wagon. The family needs to be safe and know where they are going.
I kile how this vehicle is inconspicuous and does not draw too much attention.
Increase the valve size on the engine, giving the vehicle more pickup power and allowing it to still save gas because it is so light. Also, add more luxury features, like GPS.
