I bought my prizm in 06 when it was 5 years old. It runs like a champ! The only time it's in the shop is for an oil change or new tires. The only parts giving out are minor and probably due to age. The plastic trim around the windows has become brittle, the door handles on the drivers side have both snapped, cruise control has stopped working and the drivers side window motors have worn out. Low and medium air conditioner are out, but it still cranks cold on high and the heater works great. I've been teasing with the idea of a new car because of the great deals available, but my little car is still driving great and I'm not ready to give it up! I think I'll invest in it instead!
I like the body style, it still doesn't look old. Mine's dark green and the paint is still awesome!
