I have a base 2005 (15,000 miles) with a 5 speed manual. All city driving with the AC running (honolulu) and I have been lucky to get 18 miles to the gallon. Stayed pretty much the same since new.

I have the factory carpeted floor mats and the top portion under the clutch and brake pedal will not lay flat and curls up to the point of interfering with clutch pedal movement. Any else have this problem and how did you fix it other than replacing the mat?

You are still doing better than me. I have a 2005 base 5 speed manual that I struggle to get 18MPG. This is all city and the AC running most of the time. This is in Honolulu so the cold isn't the issue
