Maserati was doomed even before they produced the Levante. The key reasons are that they didn’t have a clear vision for what they wanted to be as a company and as mentioned previously, no clear idea who their core clientele were. They tried to compete with Mercedes and BMW but failed because they are NOT that type of company. Rolex doesn’t try to compete with Seiko or Movado. Maserati tried to appeal to the masses and it backfired terribly.
Something interesting I've noticed. The brand perception Americans have about Maserati is completely disconnected from the brand's history and values.
Maserati was never a Rolex, not even a Seiko. They were a quirky brand with a very sonorous (literally) name, and that's it. They were not even at Jaguar levels most of the time - I'm bringing Jaguar here because it's an example of a successful (kinda) transition. This is no way demeaning of the brand, they have a certain heritage and image that appeals to a certain type of people, but not in the way some people in the community want.
To be honest, the idea of merging Alfa and Maserati in a single company, Alfa dealing with the lower and Maserati with the higher end of the product line, was brilliant. What else could have they done? Go upmarket and compete with- and in what segment? I don't think there is another way for them to survive and thrive, not only live in the shadow of other companies, like they did in the past, and they do now with Ferrari. There is a huge niche (if I can call it like this) for an Italian car company with a full lineup. Where Alfa ends and where Maserati begins in terms of class/size/performance is a debate that could have been interesting. Look at Mercedes - nobody diminishes the quality and value of AMG GT (or a S Maybach) just because it shares the same logo on the front bumper with an A-Klasse.
Unfortunately marchionne was only good a financial swindles, and the plan flopped.
I'm a bit skeptic about the plans of his successors, but there is nothing we can do but wait and see what the future holds.
