Was it from Gwinnett? If so I’m surprised they didn’t try to force you buy their “preinstalled” Lo-Jack.
They must be one of the highest selling BMW dealerships in the country. They have more than 100 loaners.
Honestly 15% is the average deal people are getting on loaners
The reason this one might not have been discounted as heavily as other is due to M sport + it’s a 440 and also the fact it’s a Gran coupe appeals to more people.
However saying that I do think you could have negotiated a tad bit more and cut your DAS to 1st payment only
Go on auto trader search used bmw 2019 (model) under 5k miles and then see the carfax on the dealers website link and make sure the only registered owner is the dealer and it was not registered as a personal vehicle
Also loaner can be over 5k but then they don’t qualify for new car incentices most of time unless bmwfs makes an exception
