My little ECHO has had NO problems at all, just routine maintenance.
In spite of all the jokes I've heard about my little red ECHO, I laugh all the way to the gas station when I fill my tank once/month or less often. I only work part-time and don't do a lot of driving, so this is the perfect car for me. It is comfortable and fun to drive, easy to park, the stereo is great and the A/C makes life easy.
This is my 4th Toyota, and I've noticed that the bodies on these cars seem to hold up quite well compared to some other brands. I live in PA where the winter roads are constantly coated with salt, and I've had no body-work issues, and no trouble driving in snow for that matter. The trunk in my ECHO also seems to be able to hold everything I try to put in it - a very versatile car. I've had a Tercel and two Corollas, and this ECHO is my favorite Toyota by far.
Wow, you don't drive much at all. I bought a yaris brand new 6 months ago and I already have 17,000 miles on it! I love my yaris. its the same as an echo, just a different body style. I laugh all the way to the gas station as well. I speed (80-90 mph) and use air conditioning a lot. while doing this I still average 36 mpg's. 43mpg when I drive the speed limit. (which is NEVER!!)
