Oh wow, that sounds like quite a frustrating situation. Waiting 8 to 12 months for the missing chips to be installed in a vehicle is definitely a long time. It’s disappointing to hear that GM vehicles from the Arlington TX assembly plant are being stored in a dirt parking lot without proper cover. The salesman’s assurance of covered parking to protect the vehicles from sun and hail seems to have been misleading.
When it comes time to pick up the vehicle, it’s crucial to inspect it carefully for any signs of Lot Rot. It’s always important to be thorough and ensure that everything is in proper condition before finalizing the purchase.
Dealing with delays and subpar storage conditions can be quite frustrating, but I hope the end result is worth the wait and that you have a positive experience with the vehicle once it’s ready. Hang in there!
