45K for a meh 4 banger in this class of car IMHO does not make any sense. That's an A4, not a proper roundel
Prices in general have gotten out of hand. BMW did a nice job with the high output turbo for delivering good area under the curve but I am a purist, and prefer my engines strait and with 6 cylinders in a BMW.
That's my only talking you out of it.
