These negotiations can be very complex and take into account issues which we may not be aware of or issues of a financial or logistical bases and even political and as has already been mentioned the global pandemic could have played a part too and in any negotiations once has to evaluate the good and bad points and positives and negatives prior to arriving at a decision and then such a decision has to be put forward for further consideration by the senior management team who may have other considerations that they need to be satisfied with and then finally those involved in the differing departments have to produce reports recommending it’s inclusion demonstrating the cars reliability not just on the road but in terms of financial robustness including all associated costs including but not limited to depreciation servicing and insurance and it is only when all of these points are fully satisfied can a vehicle be included. I trust this may have shed some light and clarified/answered the point’s raised in the initial post but if not I am happy to expand.
