There r two dealerships in Lahore. One at queens road and the other at jail road. The one at jail road is going to shift to Faisal town in some time. I like to go to the one at queens road, momentum motors. Didn't like the behavior of Sajjad motors, the one at jail road.
AC performance is good. Let me give you an example. A few days back, it was 42 degrees outside. I left my office at 4.35pm. I have installed a thermometer inside the car, on the dashboard, which is in direct sunlight. That thermometer can show maximum temperature of 60°C. The thermometer needle at that time was bent to the maximum extent it could go, which means the temperature inside the cabin was way above 60°C. After driving for 15 minutes, with AC, and full fan speed, the thermometer showed a little above 30°C. I was driving inside Lahore city, and the thermometer is in direct sunlight and the temperature it shows is higher than the original cabin temperature, because it is direct sunlight. So, I am guessing the cabin temperature would be around 26°C at that time. So, in my experience, the AC works well.
I have installed mud flaps, bought from model Town link road for 800 Rs, they are for swift, but fit on V2 without any issues. The newer models come with mud flaps from the factory. I got sun visors from the faisalabad dealership for 2000, they are now available in Montgomery road as well, for lesser price. I haven't installed android navigation, but a friend who also has V2 has installed it. He got for 15k, with back camera from Hall road. His experience has been good with that navigation as well. It has a 2-din universal 7 inch media player, which means navigation will be readily available in the market.
For delivery, the Lahore dealerships quote a time of 45 days and a premium of 35-45k. But you can get it on ready delivery from any of the adjacent dealerships as well, without premium, so try asking the dealers in Sahiwal or Faisalabad to get it on the spot.
