Oh, and

to the comment on 30mpg in the city... I drove like you with mixed city and highway and never got better than 24mpg. Unless you are running on the skinniest tires ever (maybe 185/45/14 haha) and reduced the weight on the car by 600lbs and put in an entire flat undertray and ran some kind of tuning software that you could lean the entire fuel system to like 15.0:1 A/F ratio and ran the thinnest weight oil and shut off the engine while coasting and getting behind semi-trucks to draft and.... you get my point.
I'm not saying you can't get 30mpg in a prelude, I got about 31 in highway driving from ohio to el paso which was awesome, but throw in some stop signs and traffic jams and the fact you hit vtec "alot" is all the proof we need to say nuh uh to your MPG claim
