Hate to Wait? Hire Someone Else to Do It

"There are a lot of different ways that car dealers are good at separating people from their dollars, because they do it all the time," Landers says.

For $395, Landers will roll up his sleeves and haggle the price of the car up from the dealer's cost instead of down from the sticker price. He'll also negotiate the trade-in value of your old car and come along to pick up the new car to make sure you've received everything you've paid for.

Considering that Landers sees roughly $1,500 of wiggle room in every trip to the dealership, he's worth the gamble if you don't have the time or motivation to do it yourself. That's what he and every Gofer Girl, Linestander and Dumpmonkey are counting on.

"There's a service out there for anyone willing to use it," Evangelista says. "We're just trying to take a difficult life moment and make it a little bit easier for individuals."
