For my experience with cars and with work, I can honestly say as much as I hate most Japanese cars, Acura is to some extent "luxurious" even tho they're an "uppity" re-badged Honda, they still have features that you would find in most higher class brands.
You can damn sure tell when you go from an Acura to a BMW what the difference is, not only just aesthetically but the whole driving experience. The FWD in most Acura's has been it's Achilles heal for the longest IMO.
And as far as being more expensive than a BMW, then you're just comparing Acura's highest equipped model trims to BMW, Audi's, Mercedes' lowest model trims. I mean comparing a fully equipped Acura TL SH-AWD with Navi etc... to a RWD BMW 328i sedan. it's not in the same league as far as options.
Compare the same Acura TL SH-AWD to a BMW 335i X-Drive with all the same options that are in the TL and you'll see the price difference.
I actually had this convo with my GF yesterday, comparing her TSX leather to my Audi A6 leather interior... it's so much more refined and elegant in the Audi, not to mention as far as everything else...no offense to her, because she's been a BMW lover/driver for years.
