Buyback Offer Received

Was curious if any of you have been able to negotiate a “customer loyalty certificate” for credit on the purchase of a new gmc after having your truck bought back.

My truck went in the shop at 800 miles and has been there since October 20th. I reached out to customer service in the middle of November and got my offer yesterday. I was hoping that they would give me some incentive to stay with the gmc brand, but no luck. The buyback amount took care of payments and balance of loan, I’m only out of pocket $500 for usage.
