Bought used with quite a few performance mods: cat-back exhaust, headers, perf. intake with cone filter, 17" Motegi rims, and lowering springs. The Integra runs great and gets 30 mpg under heavy acceleration and braking with cruising speeds around 75-85 mph. I have a medium commute to work (~30 miles) and am now looking at ways to maximize gas mileage of this reliable and well-maintained vehicle.
