Resale values is not "BS" to be exposed. If you are the kind who buys a new car every 3 or 4 years, it can be $13,000 back out of your Prelude or $2,000 back out of your Pontiac Grand Prix. When the time comes to trade in one of these gems, the resale may be important to you. If you are a leasing fan, it is also important. Banks use these assumptions to determine (guess) what they will get back when a leased car is returned, which in effect determine the leasing rate. So, if you lease, if is also important to you. Note for investors: falling SUV sales could spell trouble for banks that are heavily into leasing if the falling sales drive down used vehicle prices enough.
