I am very analytical and chose my Yaris based on reviews and talking with Toyota employees and a lot of research. I have found the car to be extremely well built and have literally had no problems with it, (knock on wood). The warranty just ran out so we will see if it does stand the test of time. I was driving quite far everyday and driving about 70/30 highway and getting (even w/ the A/C on) about 36-37 mpg with the Yaris and it's an automatic. I am a bit of a lead foot too. So I would recommend this to anyone looking for a reliable, efficient and cost effective car. Keep it maintained and it should last no problem.
The small glove box on the drivers side, too small for much but easy to get important things.
Make a hybrid model. Make the front seat bigger and back a bit smaller. I'm almost 6' tall, if I were any taller I couldn't drive the car.
