I have had this car for 4 years, the old wagonR r was 100 times better, I had that lovely car for 11 years. The mileage mentioned is totally wrong. the mileage I used to get was 13-14 with AC on in city and around 15-16 on highway, I being a doctor my driving I feel was safe and good,, the engine has problems got to hear it from friends and issues with my car also, servicing was ok ok not so great. If I keep specifying about each and every part then it may take around 3 days.
My sincere advice is to do a lot of research and then only come to final decision.
