That’s a nicely equipped M550i. Please don’t forget to add the color combo, options, and photos. The window sticker would be very helpful too. The transfer fee is actually $500+tax, not $350 (you might be thinking of the disposition fee). Also don’t forget to mention this car has Ultimate Care+ because that is a huge plus. The “Prepaid Maintenance” is vague because some people might think that just refers to the regular maintenance plan that comes with the car. GLWT!
I can’t show you a better deal because I don’t have one, never implied that I did. And if we are comparing “apples to apples”, you would have to include the 4K DAS on the M3, the same way you would be including it here for this M550. I’m in no way bashing the OP, just stating my opinion.
Simply put, IMO, because an M3 is a true “M” vs the M550. Either way, they are two completely different caliber of cars. Your question is very much valid.
