The car fuel plays a significant role in determining the price of the car – price is one of the major factors that buyers prefer one car type over the other. While the diesel variant was targeted at commercial users like trucks and min vans till about a few years back, today, automobile makers come out with both variants of the car except for few low-end models like Alto and Kwid because there is rising interest in diesel passenger cars. There are obvious pros and cons with each type which one needs to evaluate well before making a purchase.
