Dude, you're asking this question on a BMW forum
Personally, as the others have alluded to, I would never buy a car make that is an upper scale subdivision of a parent company. If it's basically the same car/platform why make it a second time, under a different make? To pay extra for the name? BS. The performance and features of a Lexus should be offered on the equivalent counterpart by Toyota, Acura/Honda, Nissan/Infinity etc. ad nauseum.
