Perfact family van

I have driven my modified 5 str ac patna to rishikesh and hisar about 3000 km . Very comfortable to drive and easy in between traffic. Not a single vehicle problem. But I have faced some other problems as above 117kmph speed ,bubbling starts . Other My vehicle is modified to 7str for my joint family so two times I have to pay fine. Because during purchase I have to choose between 5str ac or 7str non ac.So request company to build 7str ac for joint family and make rear door latch from inside with child lock. Yes one more thing when long drive at rear sleeping floor is available for children.
