Can I add a service contract or warranty to my car loan?

Yes, dealers often offer to finance extended service contracts, GAP and other products in the loan. They're optional, and you'll pay interest on them if financed. Ask for each product's price separately, read what it covers, and remember that you can usually buy similar products elsewhere or decline them entirely. On OffLot, protection products are clearly optional choices in Build your deal, so you can see how each affects the total.
