Buying a diesel car makes sense only if your daily running is more than 60 kms. Bust since your upper limit is Rs. 5 lakhs, for a total of 1500 km travel per month, you should go for a cheap diesel car. Barring the Indica/Vista, the only other diesel cars that cost approx Rs 5 lakhs are the Chevrolet Beat Diesel and the Ford Figo (base versions of both cars). While the base version of the Beat would be around Rs 4.95 lakhs, the base version of the Figo would be around Rs 25,000 more expensive depending on the state/city of your residence. Test drive both cars and decide which one suits your requirements better. The Figo has a four cylinder engine as compared to the Beat which has a three cylinder engine so in the long run, The Figo engine would remain more refined.
The best petrol car in your budget is the Honda Brio S(MT).Go for it if you want to opt for a petrol car instead of a diesel..
