My husband, the car fanatic, loves to go look at new cars just to see all of the new features that manufacturers come out with every year.  His dad is a salesman so when he has time, he shows my husband some of the new cars available.  Since it is a hobby of his, he gets a lot of information about them from his dad when he visits.  Car Dealers are up to date on the latest trends in new cars and they are able to relay that to their customers.  My husband loves getting all of the information about new cars.
