My 93 Civic LX has >130K miles, and STILL gets >30 MPG! DOHC engine still very quick and reliable -- cruise very comfortably at fast speeds (would NEVER do with other older-mileage vehicles). Mechanically excellent, but some of the interior components starting to deteriorate after 13 years (LED on stereo, speakers, plastic door handle snapped, spring clip for wipers). Recently test-drove 2003 Civic EX -- difference in performance between 2 was negligible -- I was quite surprised! (Or maybe I couldn't really "test" it because salesperson was sitting next to me). Best car I've owned yet!
Tight handling, fast acceleration in low gears, easy-to-shift gearbox, comfortable ride for the size.
Seemed to chew up CV joints -- had to replace them twice; had some roll on cornering; road noise at higher speeds.
