Being a premium manufacturer, you can expect owning a new GLA-Class SUV or other vehicle from Mercedes-Benz to command premium prices. While we always like to talk about how much it costs to buy one, the truth is that once you have overcome that hurdle, the cost of keeping a Benz on the road will immediately become apparent, especially when it comes to servicing. Take your Merc to an official Mercedes-Benz dealer, and you will experience top-notch customer service and a wealth of knowledge about how your car should be kept in tip-top condition. If you do decide to go ahead and get your car serviced, however, you will be asked if you require Service A or Service B.
