well... initially got the FIT because both of my CRX were putting up crazy mileages. i do about 100 miles a day. soooo... i obviously needed to get a car that was reliable. had the car for almost a week now. like the feel... but still not used to the "new" car feel. just wondering though... how the jdm version claims it gets 48 mpg on the hwy and the usdm ver. only gets 38 mpg hwy? besides the 200 pounds of weight difference and the 185 tires to the 195/55/15. is there something that the japanese version has or less restriction than the usdm version that it gets way better mpg on the hwy? i'm on the hwy like 90% of the time with the FIT. thx.
