Too often, people equate PM's lower price with lower quality without understanding its history and concept.
In the early 2000’s, Fiat, Peugeot, and Citroen collaborated on a new van body which debuted in 2006 as the Fiat Ducato, the Peugeot Boxer and the Citroen Jumper. Each had its own drivetrain and maybe some minor cockpit differences, but that exact body has endured unchanged through the 2022 Promaster, and even to 2023 except for the modest changes to the front end, mainly the hood. My exact 2014 build would fit a 2023 Promaster or a 2006 Ducato, Boxer or Jumper.
This uniformity, not lack of quality, has contributed significantly to the PM's price advantage. Also note how the various size options play together for ease and economy of manufacturing. As a simple example, a Safelite rep told me in 2018 that there were 14 Transit windshields. Since 2006, there has been exactly 1 windshield for all Ducato, Boxers, Jumpers and Promasters.
I, for one, think the PM's design is pure genius. I have to say that since you'd never guess otherwise.
