My Echo is best car I have ever owned. Totally reliable. 6 years and 192000 miles driven & all I have had to replace is a thermostat. I do keep on top of the maintenance. The inside is so roomy I don't feel I am in a small car until I see another Echo. The sound system is excellent. I would have preferred a little more body style and would have loved it if I could ever have achieved the milage of 43 mpg mentioned on the sticker. Small cars usually have no "get up and go" but the peppiness of the Echo is incredibly impressive. I love my car so much I wanted to purchase another. I was devastated when I found them dropped from the line.
The performance & reliablity. Regular maintenance and she goes and goes and goes.
Body styling. Some of us older people like an inexpensive small car that looks good, drives well, is economical and doesn't look childish. Some additional colors.
