The basic CPO coverage is 1 yr/unltd miles beyond factory warranty. You can buy it up to 5 or 10 years. Just ended up buying a new (never titled) 2023 XC90 w 200 miles at a big discount & got a 10 yr/120 k new car EW for $3950. But we were also looking at a low miles 2023 CPO and the quote for 10 yr extension was $3450. That was for the Platinum level which covers anything not on an exclusion list (mostly wear items w an expected life cycle limit like brakes, clutches, bulbs, belts & hoses.). The prices on EWs are a bit flexible!
