if na and a honda, i would say... 50k u can get a original eg6 or eg9 - or maybe an EJ (local EK) convert to b16a/b18c etc etc.
fuel consumption? well, i believe its stated above bro, if u want performance, fuel consumption would be out of the question.
perhaps like the others mentioned, satria/wira mivec perhaps? definitely cheaper than the honda range...
all in all, i would say, every car has "decent" fuel consumption, it depends on how u drive it only... but of course the newer cars will clock better mileage as compared to the older generation..
just my 2 cents =)
