Which car from among the Maruti Ertiga, Mahindra Quanto and Renault Duster will best fulfill my requirements of good performance, fuel efficiency and ample space?

AAA:  The three cars you have listed are quite different and excel in different areas. The Ertiga is the most fuel efficient, the Quanto is the most spacious and the Duster has the best performance. However, as an overall proposition, we prefer the Duster because it drives better than the others, is reasonably spacious and is well suited to Indian roads. The Duster is also the most expensive and its prices have been raised further recently, but we still think it’s worth the premium you would have to pay over the others.
