I bought the Yaris mainly for reliability and gas mileage and so far the vehicle has been good for this. BUT there are some issues that I wish I had known about before purchase. They are significant enough that I may have chosen another vehicle. 1. You cannot drive with the windows open because of a strange sound effect that hurts your ears. 2. The sounds system is TERRIBLE. 3.Cup holders in TERRIBLE places. 4. Air smells like dirty feet when you turn it on. On last oil change they found NO cabin air filter. 5. Just plain too small. My teens cannot sit in the back seat so we have to take TWO cars on trips. There goes mileage savings.
Gas mileage, reliability.
Change cup holders, sound system and a BIT more backseat room even at the expense of trunk room. SLIGHTLY taller ceiling would go a LONG way. Figure out why windows open are so awful noise wise... something in the engineering is off.
