I'm looking at purchasing a new 5.3 liter motor for my 2010 GMC Yukon XL with 157,000 miles. The dealership says that my old motor needs to be returned to GM or the dealership will be charged a $3,500 core fee by GM. Is this legit or BS? They are quoting me $10,000 to remove and replace the motor with a 3 year manufacturer warranty. Any help would be appreciated.
Thanks
