The CX-5 is the crossover for people who actually like driving. It feels more expensive than it is, but maintenance is still reasonable. You will see the lowest prices in late December when dealers need to hit annual targets and clear space for new models.
Expect to pay around $19,000 for a solid used model. We recommend negotiating the total price first before mentioning how you will pay. You can use a specific card window for a portion of the cost to avoid interest for over a year.
This is a 15-month timeline, not free money. If you still have a balance when the 15 months end, you will start paying the standard variable APR on whatever is left.
