0 Problem with the 03 except a dead coil first week I bought it and regular maintenance. Car had 104,000 bought 2 years ago and now has 119,000.
For the 2nd on the 00 ZX3 bought 2 weeks ago with 169,xxx on it , did nothing to it except cleaning the car , I drive it everyday since I bought it , 500km per week , runs like new.I'm the 2nd owner
I haven't paid attention but it's about right , i can barely make a full week with a tank , they are not the most economical cars but so far they are pretty reliable.
