This debate about petrol Vs Diesel car has been raging for quite some time now. However, based on my personal experience having driven both petrol & diesel cars I strongly recommend petrol cars. Mainly on two counts viz. Petrol creates lesser pollution & petrol vehicles are easier to maintain. It costs much less to maintain a petrol vehicle as against a diesel vehicle.
All in all it really makes sense to go in for a petrol vehicle especially since pollution is such a major cause of concern.
We all should promote use of petrol vehicle as it is more environment friendly when compared to diesel vehicles.
