what a troll and bro which jugaaru mechanic told u all this bullsh**? he should be awarded ****** bag of the year award. if there isn't a 4th spark plug in vxr/vxl' s 4 cyl engine does the 4th cylinder run on diesel?? someone made an idiot out of you. the efi of cultus is simpler and more reliable than carby as there isn't auto choke, hydraulic tappets etc.. present in it. and difference on cng?? try moving a carby cultus on cng a/c and 5 people on board from stop in 2nd gear you'd know the difference, although paint and finishing quality has deteriorated over the years there isn't any difference in strength of body, road grip. and vxr's engine hardly makes 50hp while efi engine has 60 hp. vxr can't beat even a santro while vxri does that with flying colors and how can u say that a 8-10 year old used ride would be less problematic than an efi vehicle(which has less chances of being mis-tuned hence if there is any mechanical problems one can find them immediately during test drive).
