Most car buyers and most dealers, if they are honest, know that are largely a waste of money. Statistically few buyers will get the full value out of their coverage. This is a problem for the dealer's finance office, which makes money from these add-ons, so they are coming up with new tactics.

According , about 50% of car buyers turn down extras in the finance office like service plans and extended warranties. Now that Internet shopping tools have made new car profits shrink — dealers have to compete more with pricing thanks to TrueCar and other sites — the dealers have to find a way to make up for that loss. Often this money is found in the finance and insurance office. An NADA report said:

"F&I accounted for 38.8 percent of gross profit for dealership new- and used-car departments combined in 2013, up from 36.9 percent in 2012, according to "NADA DATA 2014"....That was the fourth yearly increase in a row. It was also part of a gradual increase that has lasted nearly all of the past decade."

Despite this growth, more customers are getting wise to the cost benefit analysis of these extras. A survey revealed the following:

Are extended warranties for cars worth it? Read the results of a Consumer Reports survey and learn…

"55 percent of owners who purchased an extended warranty hadn't used it for repairs during the lifetime of the policy, even though the median price paid for the coverage was just over $1,200. And, on average, those who did use it spent hundreds more for the coverage than they saved in repair costs.

Among survey participants who used their policy, the median out-of-pocket savings on repairs covered by extended warranties for all brands was $837. Based on a $1,214 average initial cost, that works out to a net loss of more than $375. Factoring those who didn't use their policy, the median savings was zero."

Now dealerships have to come up with a way to capture these lost opportunities. Eric Marcel runs a consulting firm that helps dealerships track revenue loss opportunities including those in F&I. He says that data and following up are key to getting these customers to finally come around.

"F&I should run this report weekly at least, if the manager is hungry... Just because a customer declined to buy an aftermarket product during their vehicle purchase doesn't mean the value of that product or products isn't still valid for them."

"Half of our customers leave F&I without purchasing a service contract, but our follow-up efforts net a 10% return...For our Nissan and Subaru dealership, this nets around $10,000 in recovered revenue a month, and customers fulfill 95% of them, so there's good stickiness." - Mike Breen, the dealership marketing and IT manager

So the lesson to consumers is just because you held your ground in the finance office, don't let your guard down. More and more dealers are following up to push those products that may or may not be worth your money.

There is a reason these products are so profitable. For every out there, there are hundreds MaxCare covered cars that will drive for years without any problems at all.
