Is an extended warranty worth it on either of these?

Both vehicles are out of factory bumper-to-bumper coverage at this point. Combined repair exposure across the top problem categories runs around $12,050 on the higher-risk vehicle. A quality service contract typically costs $1,800–3,500 over 3 years, so a single major failure usually pays for the contract. The math favors warranty coverage on whichever vehicle you choose, especially if you plan to keep it past 100,000 miles.
