It's allowed in the USA. You can have multiple models on the same floor with the same salesperson selling all models.
Exceptions exist, i.e. new car dealers (who contract with one company and can only sell what is stated in their contract).
How strange. A contract demanding you sell only from one brand isn’t legally binding. The manufacturer would have to open up their own store if they want to only sell their own cars.No. New car (not used car) sales are fairly regulated.
And I’m talking about new cars delivered directly from the manufacturer
