yeee khyber is indeed the bst...i hav 1999 late limited edition khyber...and i love it...it can beat all mentioned cars...can also beat efi cultus on 1st gear...but then its harder on 2nd....
the reson is that khyber is the only 3 cyl 1000cc car...so 1000 cc power is divided to 3 cyl..instead of 4...
AAP khud patahoo k agar 1 roti 3 bandeh kahe tu on ka pait fill hogah..aur agar 4th b agahe tu roti ka share aur kam hojahe gah...which means less roti to each=less energy of each/less acceleration of cyl
