Hi Mr. Rakesh Kumar Narang,
This is in regards to your query posted on the website CarDekho.com, we would like to inform you that Toyota Etios bookings are open at all Toyota Etios dealership, Booking amount of the car is Rs. 50,000/- and you can book the car as soon as possible to get the delivery soon. Toyota Etios is on 4-5 months waiting at present.
lpg kits are approved via govt of india. UNITAX is best bec its cheaper kit and isi approved only cost 9000rs from 900cc to 1500cc vahicals + 2500rs extra for government approval on your RC.
u can install lpg kit in any patrol car.
etios is just a entry level sedan in Australia ppl do lpg conversation on almost every high end cars like ford falcon holden commodor toyota camery etc. bec lpg is cheaper.
and 100% taxis run on lpg I had a toyota Rav4 fitted with Lpg converson kit.
Both Toyota Etios and Swift Dzire are good options, while the Etios has space, Swift certainly has a powerful engine, better interiors and after sales services. The Dzire also enjoys better resale value.
