Good to see all the interest in the JDM cars being imported.
I bought a Suzuki wagonR 2007 more than a month ago. Pleasure driving the car, so far no problems whatsoever.
16.8 ~ 17.5 (with ~ without AC) in city.
Took it on motorway and almost the same average.
3cyl K6A 660cc engine, with 4AT - with overdrive gear box
comparing these with any paki cars, I'd say the way they have utilized the space is awesome. The legroom for all four passengers is so comfortable, it's unbelievable. The rear seats are fully adjustable, i.e. they recline as well as move forward and back.
let me know if you have any further questions regarding the WagonR.
