The main reason car companies update their cars is A, get people to buy a new more expensive car, B,, incur more debt. Most car manufacturers have a lending component. something-Motor Credit. Make no mistake, those are banks and they make a hefty profit on your loan.
This is the way it works: You finance a new car. You use it for 3-4 years, but now those accumulated stains, door dents, a few rattles and such are bugging you. So you go back to the dealer who miraculously offers you an incredible offer for your car on a trade in on a new car at a slightly higher payment.
And there you go in a new car with no stains dents and rattles and the latest Bella and whistles. But you also are driving off with a new loan with higher payments that is going to take longer to pay of then the original loan. XYZ Motor Credit is thrilled as their loan portfolio just expanded and your payments are now secured for additional years.
Innovation, not so much. It’s all about lending money for a profit, like any bank. Cars are just the impedes to make these deals happen.
I’m not so sure this is a good model of operation for musical instrument companies.
