This is what they sent me in response to my asking it in writing. Does not mention anything about make of rental car or limitations, she confirmed all that over the phone that I can get a seven seater of any make (there were no GM seven seaters to be found) and at any rental. I rented a Ford Expedition form Enterprise and never got reimbursed.
We are pleased to be able to offer you a reimbursement for the vehicle you rented during the repairs on your 2021 GMC YUKON XL, VIN .................... at ........ Buick GMC.
In order to get this processed for you as quickly as possible, we need a copy of the repair order from your GMC dealership showing the date the vehicle arrived at the dealership and the date it was repaired.
In addition, we need an itemized copy of the rental agreement showing total charges. GMC does not pay for additional insurance or fuel.
Lastly, we need proof-of-payment for the rental invoice, which can be satisfied by submitting the front and back copy of a cashed check; a credit card receipt that identifies payee, payer, and paid amount; a bank or credit card statement that identifies payee, payer, and paid amount; or, the rental invoice marked paid and showing a zero balance.
For your protection, please blacken out any account numbers or other personal information. As soon as we receive this documentation, we will process your reimbursement, which should arrive in 6 to 8 weeks. If you have additional questions, please respond to this email or contact me at the phone number and extension below.

I assume this is a standard email sent out. So I was at the mercy of GM honoring their word... as I mentioned, it's the violation that bothers me more than money...
