I do not know how the Subaru sales man program works (if one exists) but I had a cousin who went to work for a Chevrolet dealer. Started out in used cars and got a rep for selling s.u.v's and pickups. When presented the opportunity to move to the new truck sales division, he had to take gm created online classes accessed only at the dealership in between truck sales and get certified by gm as a Silverado sales expert before being allowed to sell the new models. Every year, he had to re-certify in addition to take refresher classes ranging from the small changes between model years, salesmanship strategies, etc.
He told me it was intense and rigorous with everything from dashboard layout, how to use the radio, under the hood layout, horsepower / torque / pulling ratings/ mpg, option tiers especially what options were available with which package tiers, competitive advantages when compared to f-150, ram, tundra, Titan, and his case even GMC, etc. Even the post-sale training was brought up where the salesman sat with you and went over where everything was located at. Was a part of the curriculum.
But my Subaru salesman was sharp and was very knowledgable. He did the one week follow up call one foggy morning where I could not remember where the fog light switch was and he instantly told me to look on the turn signal lever and look for the letter d with the lines. Question answered. I do not know if he sold so many subarus for so long or went through a similar training program but he was very knowledgeable about the car. The dealer I purchased mine from was also the Volvo dealer and in my salesman's cube he had many certificates of certified training on various Volvo models.
