Got the car 3 weeks ago and just hit 1000 on my 18 Si. Been averaging 32.1 in mostly city driving! Having a couple problems with it though :/
Tuns out it was just me being unaware of the infamous 2nd gear clunk in the Civic's! Took it to the dealership and they told me it should be smoother once broken in with more miles on the car and to also change the transmission fluid every 15,000 miles.Sorry to hear that! What issues are you having?!
