People may bash it for its styling, but over all the civic si is a great car. Its very comfortable, has a very good sound system, does great gas mileage (if you drive it nice) and it was a extremely powerful heater! Mine is the "mustard" gold color and man does it turn some heads. People think that the "Dash Shifter" is ridiculous but it is honestly very comfortable to use when driving. It's got more than enough power for you to have fun with. Although it doesn't have "True Vtec" its i-vtec design is very good giving the car good power in all gears. No need to down-shift from 5th on the highway to pass someone, it still pulls like a train giving you easily enough power to pass something.
"Dash" Shifter! I love the color (Goldish, not everyones favorite) Fuel economy, Its basic-ness, powerful heater, the amount of room with the seats down, power in every gear, turns heads, great turning radius.
Maybe a little more power (put the jdm civic type r k20a2 in there) Make it look a little more aggressive (jdm type r front/rear lip) Maybe some bigger wheels (added later to late models) After market HFG package through honda is very nice and makes the car look a lot more aggressive.
