The point is not of prestige but of affordability, but those who cannot afford petrol, how come are able to buy expensive VTIs??? I think people who have got VITs are through leasing are going for CNG otherwise one who can afford a 13 lakh rupees worth machine, must have no problem in running it on petrol. BTW my Corolla XLi is on petrol, so those saying that only Toyota wallas go for CNG are also wrong
