The price diference is about 90,000 betweem VDl and VXl models. If l buy a petrol version, l have th eoption to put a CNG kit infuture, whreas for Diesel l may not have this cjance. Please advice.

The thumb rule to decide between a petrol & diesel car is, that if u drive less than 2000 km per month, then ou should go for the petrol. On the other hand if u drive more than 2000 km p.m., diesel should be the choice. Otherwise the extra cost does not work out. This is the normal recommendation by many car experts. Adding the CNG would enhance the economy but just make sure that u fit only factory recommended ones so that u wo not lose any warranty.

Hope this helps.

petrol is the one to go
diesel is costlier and noisier than petrol though faster
