I would take the maintenance plan over the extended warranty anyday. You're going to have a warranty on the repairs they did anyway, along with the standard warranty.
But the (extended) maintenance plan could be worth more to you in the long run. Especially if you plan to trade the vehicle in 3-4 years. That extended powertrain warranty won't do you nearly as much good as somebody doing routine maintenance for all that time without costing you a dime in the process.
S.
it will if the truck continually has problems. i would way rather pay for a 35$ oil change than a entire ******* motor 300 miles outside of factory warranty.
