Of note, I had a conversation with one of the representatives who offered a pretty decent deal to upgrade to a 2023 BMW 740i (XDAR class) for $100 total for a 2 day rental. Given the rate for the original 5 series reservation was so low this would have been close to $250 USD for 2 days in the 740, just over half the going rate even with platinum discount for that class. Ended up declining to have the slightly smaller and more efficient engine for the trip, but was pleasantly surprised to see a competitive enough offer even though they were relatively busy. If the upgrade (or a similar upgrade) were to be offered at no cost I would have been more inclined to accept it.
