You need to get your Mercedes Benz car serviced from time to time.
Whenever you visit a Mercedes Benz workshop for servicing they provide you with an alternative Mercedes Benz car to use until the servicing of your car is done.
The company follows this policy as part of their marketing strategy, so as to maintain a good relationship with the customer. The customer’s comfort is just as important to them. This is the reason why most Benz dealerships offer loaner cars.
I enquired about this with one of the company's personnel and he said that “During this time period of servicing if the customer rides a BMW or any other car and finds it better in some way or the other than Benz, then this is a loss for the company.”
Indeed, customer relationship matters a lot for each and every brand in the market.
