GMEPP after the fact
I have a 2017 suburban bought about 18 months ago. I am looking to get the GMEPP plan added on to it. I remember reading that the price increased substantially after 2 years and either 20k or 24k miles.2 questions:1. Is it 20k or 24k miles that I should buy the plan before reaching?2. Best places to buy it from?
