Do most people buying a car these days care if a salesperson can tell them all the tech specs about a car ? I think not.
If dealerships catered only to the knowledgeable "gearhead" types they would go out of business.
Most people buying cars are more interested in their monthly payment on the mininvan and how many cupholders they will get with the latest model.
Having said that, anyone with any love for their job would learn everything about it and use that knowledge as necessary. And it is funny to hear some of the BS salespeople try to pull off.
