7. Some car options don’t have to be bought as a package.

Dealers make a good amount of profit by selling car upgrades. Instead of buying a $2,000 navigation package with a bunch of stuff you don’t want when you only want the backup camera, you can often get the backup camera installed via a third party vendor — and still through the dealer — at a much lower cost, says LeeAnn Shattuck, who helps women negotiate car prices. Shattuck says she recently did this for a client on a new Nissan Juke.

She also often has the dealer “add leather” to the base model car for a client who wants leather seats but doesn’t want to pay $4,000 for the “limited” or top-level model of the car with a bunch of other upgrades. Leather for the front and back seats, and door panels, can typically be added through a third party vendor for around $1,000, Shattuck says. The leather is of equal or better quality than the factory leather, and typically comes with a good warranty, she says.
