Worst Service and Maintenance

Buying, Driving, Looks and Interior are good at this price. But, when it comes about service and maintenance. The team is only trying to achieve their OW spare selling targets rather to resolve customer complaints. My car has completed 81000 KM and the service center people pitched me 42000 cost on service(Suggesting: Shock Absorber, Mounting, Whole Brake system, AC Belt, etc replacement; while when get checked on another SVC, they suggested only mounting). Note: Am getting serviced my car at every 10000~14000KM on regular basis only from authorized SVC.
