I have been using Maruti Wagon R Duo for the last 4 years.
It runs on both on petrol and LPG.
LPG costs just about Rs.35 to 40 per liter in Chennai while petrol costs is around Rs.65 per lliter.Thus, when running in LPG, it is one of the most economical cars in India.
The pros:
1.Most economical car
2.Brand name of Maruti assures good resale value.
3.Reasonable price
4.No shortage of spare parts or service centers
cons:
1.Very light body.
2.Less Dicky space due to the LPG Tank.
I am satisfied with the overall performace of this car and hence recommend it as the best car at the entry level, for a small family
