I bought it new in 1998 and 8 years later I still love it. Fun to drive on trips and at the track. Very reliable. Have had minimal repair issues, significant considering my 25+ HPDE's. Basic suspension mods really helped the already excellent sport driving performance, and a Quaife LSD has been a good investment. Will hold 0.9+ G's in a flat turn, and can reach 150 mph without much trouble. Impresses the BMW and STI drivers and can hang with much higher rated cars in the turns. Best looking and most elegant styling of Honda ever. Ford and others have recently picked up its more notable styling elements.
Handling, styling, reliability. Street driving was excellent, but track driving has been better than I could have hoped for from a $21k FWD 2.2L car. Regarding handling, several passengers have told me "my car could never have done that".On top of all this, driving it is still very affordable.
More room in the fenders for wider tires. Stronger brakes and air ducting to help with heat build-up, lower seats or higher roof for more headroom, more CARB-legal aftermarket support, tuneable ECU, seats that provide better lateral support, redesign the autotensioner.
