I think that they have a high labour charges because of low volumes. However the number of vehicles serviced per service centre should be definitely comparable to Maruti or Hyundai. 1050 for fitting reverse parking sensor is very high, and also the cost of sensor itself is high. There are reverse parking sensors listed in ebay 900 upwards. I think it is a well known fact that the car as a product as such is better than competitors which is why I bought one.
