Reverse gear is not stuck, we just need to find the right direction to move the gear lever, I also faced this but then at first it was even hard to shift to first gear but now after some running i am now comfortable with forward gears. So i hope after sometime i get used to shift reverse gear as well.
B/w I am enjoying my ride Alhumdulillah, its build quality is good, AC is excellent, seating position is very comfortable, suspension is also good and not much body roll on uneven roads, less than my expectation so its great. Only if suzuki adds ABS, power side mirrors and make back door window auto, people will be willing to pay more.
I see very less WagonR on karachi roads till date so its a head turner
and it make you feel that you actually driving a new car, it will never happen on new car that is not newly launched.
