That would be my suggestion also
Everett is " the home of the 100,000 mile powertrain warantee " when you purchase new from them. They talked me into a "wrap around warantee that was also 10 year 100,000 but covered everything bumper to bumper. It cost me like $5,000.00 I do not think that any of there big 100,000 mile warantee deals are transferable to another owner. Just the ones from GM and there only like 3 years and like 36,000 miles.
Talk to the dealership
