Wow, thanks for all of the great replies!!
I called the local dealer that oddly still has 4 MSPs on their lot to see what the story was on them.
I was told that, apparently, there was a string of headunit thefts from these cars on dealer lots...all over the country. There was a thread about these specific cars and this dealer in this site's forum for my area a while back. The dealer is still waiting for replacement heads due to a huge backorder on them.
So, knowing that, should I still bother for $16k usd, or dicker for less knowing that they're already been vandalized to some extent?
My apologies if this particular tangent should be a separate thread. Mods feel free to move/delete if that's the case.
Again, thanks soooo much for the great words, everyone! I had no idea so much info would show up in just a day.
