I bought WagonR - Vxi from Pratham motors in 2007. Before buying the vehicle I met almost all Maruthi dealers in Bangalore finally I choose Pratham Motors.
I really liked their pre & post sales support, their process and the way they look for customer satisfaction. They have express service option, free pick-up for female owners. They remind you on your vehicle service due date. After delivering the vehicle they check with you whether u satisfied with the service or not.
U should go thru their process (which u can do by going through the white boards fixed at each and every service area). Really customer focussed service engineers. Their Wi-Fi reception area was really good. U can use your laptops while watching the way your vehicle is getting serviced. If any one of you are planning to buy any Maruthi Vehicle I would strongly recommend Pratham - the best dealer in Bangalore for all Maruthi products.
