Years ago when I developed the Luxury Index pricing tool, I was able to forecast massive value increase opportunities in cars – both new and vintage ones – and the fact that Mercedes now crowns automotive value creation ahead of vintage Rolls-Royces and Ferraris underlines the intrinsic power that the brand has created over decades.

The push will put the S-Class, Maybach and AMG closer to the brand’s centre, as well as the iconic G-Wagon, a car in astronomical demand with long waiting times in markets like the US, where people are willing to pay thousands of dollars above the asking price just to get hold of one.

When I visited Casa Cipriani in New York recently, one of the cities’ most exclusive private membership clubs, there were 10-15 G-Wagons parked at the entrance, indicating how popular it is among the young and affluent.

In some cases, almost too popular. A friend of mine who drives a G-Wagon recently told me that “they’ve become so common, I think I will buy the Lamborghini Urus next”. Mercedes will have to adopt the fashion playbook and create frequent limited editions around their most desired cars to keep the audience interested over time, creating more collectibles, like in haute couture.

And the brand will need to continue being bold. The EQXX and cars like the Mercedes-Maybach Vision 6 or Virgil Abloh’s Project Maybach, designed in collaboration with Gorden Wagener, the design director of the brand, should not just stay concepts, but become a production reality. This will set Mercedes apart and offer exclusive alternatives for a clientele who wants to differentiate from others through the brands they buy. Combining exclusivity with defying norms will be critical.

The other area that will require extreme attention to detail is the service experience at showrooms. My own experience at Mercedes dealerships in the US, Europe and Asia has been underwhelming at best. I never had any brand experience I would rank as close to a mind-blowing luxury one.

Mercedes will only succeed in becoming a “haute voiture” brand if the service is truly luxurious and different to what BMW, Audi and Porsche offer. To my mind, lots of improvement is needed here.

Even worse was the experience of William Farah, a successful lawyer and influential restaurant owner in Michigan who recently bought a fully loaded new S-Class. What he described was a complete breakdown of the showroom and brand experience.

He told me that, “Immediately after I bought the S580, electronics were not working properly, then the car locked me out, wouldn’t turn on and I couldn’t open the gas door to fill it up. The showroom had to rip the gas door off, so I could fill up and drive home. I was meeting an important client at their house and the car was stuck in their driveway. Since then, the gas door is no longer flush with the car, despite being in service forever to fix it.

“Then I had more problems: same issues, locked out at a restaurant with my wife and kids. More than a year later, while the issue seemed initially close to be solved, I am still driving around in a defective car. Mercedes-Benz corporate is nonresponsive and the breakdown in showroom communication is remarkable.”

His experience may not be indicative of the overall quality of showroom/client interactions, but it underscores that to be the “haute voiture” brand, every detail of the client experience counts. In luxury, there can’t be mistakes. If a client has issues and does not feel valued or taken care of, then there is no luxury. And when the client is influential, word will spread.

Mercedes-Benz is on the right track with its strategy in my point of view and its lasting success will depend on excellence in the execution of the whole brand experience. It will be exciting if the brand can balance out these challenges, create a truly unique client proposition, and avoid service issues like the one above. Otherwise, Farah’s next car may not be a Mercedes despite the brand calling itself “haute voiture”.
