Ns automobiles is located in mahim, I have bought my bajaj pulsar 135 from these guys and I have great satisfaction with their customer service since last two years. initially I had bought at 54k from them and it was provided with 12 free services. during the free services the mechanics were really patience and made my bike to be in fit condition. from the last year I have been paying for my service and still the maintenance cost is very low on an average it just cost around 800-1000 rupees per month. but make sure that you have to take an appointment before the day you take the bike to the service centre. the best part of ns automobiles is that the spare parts as well are available in the showroom itself, if you have a pulsar and you are around mahim jsut rush to ns motors. ther are the best in this business.
