After looking around for a long time, I finally purchased the Wagon R Duo LXi in March 07. Well the is doing really well, as u expect with every new car. Its a pleasure driving the car.
In the first month I ran the car for about 700 km, I found the milage to be near 12 kmpl(coz I drive mostly late nights n empty roads;)) . Of course on LPG the power is a bit less, but is good enough in city traffic. the car goes up to 60 with ease, thats the max I have driven it to. The EPS makes weaving through the spiral roads(coz all roads are dug up) quite easy .
When I first drove this car in petrol mode I found the difference between petrol and LPG . The engine makes a little more noise in the LPG mode, the car looks like it is struggling a bit. putting in more effort. Whereas on petrol this car flies on road . It runs like a hot knife through butter.
About the LPG tank . I have put in 23 litres of LPG in it, and hence I believe the capacity is more than that. Also its highly economy since a tankfull costs aroung 600/- and I usually run it 250 kms with that fuel. so its increadibly light on pocket.;)
I have also noticed some problems
in 3rd week, all of a sudden the car refused to start. On calling the Maruti Onroad service(the tecnician was pretty BAD) the technicain could only temporarily start the car with a jump wire, At the service station, they found no problem except a loose wire. This problem didnt occur since.
The fuel tank / spare tyre jumps on bumps .
The LPG indicator is bad. I rely only on the trip meter .
The features are different for DUO Lxi and petrol model.
All in all I would give a thumbs up to the car.
Start the car and put it in reverse gear causes a jerk.
PS Please be careful with the dealers . I practically visited all of them and they just line your path with traps with extended warranty, service contracts, accessories. BE CAREFUL of the dealers
