80k for M4 is also totally overblown. The 4 series is very recent - I've actually never seen one in Germany up until now.
Really? Even though it was still missing features that a Chevrolet had? Like satellite radio, a heated steering wheel, and ventilated seats?
You can easily get an M4 up to $90k ($100k+ if you make it a convertible).
The M4 is basically an M3 - they've been around that price range for quite a while. What else can you obtain with similar performance numbers and fit and finish for "way less money spent"?
