sorry for the late reply bro... as you know.. havent been getting much time to visit/reply to threads.
-talking about fuel average... well... before i sold mine.. it gave me around 8km/liter in-city driving WITH AC.
i was not able to check the average ever without ac.
and on cng... my friend has one.. it gives him around 85-90km with ac on a 650rps tank full.
-now about parts.... yes parts are easily available. specially used parts (shershah)
-the only difference that i saw in 98-99 spec and 2001 spec was the seat and door panel fabric.
-and yea.. they are pretty fast... mine was about 2cars length slower then a brand-new civic prosmatec on the q/t mile.
-comparing to the predecessor... a friend also has this car... and honestly i would not recommend it.. main issue is the parts... parts are very rare for the 94-97 accord.
now to the cons.. the only reported problem in cf3's here in pak is a auto transmission issue. although i never faced even a single issue... but people have said that their transmissions have failed...
so my advice would be.. when you search for one... just make sure the transmission is in good condtion.
