Congrats on the new ride!
I think it sounds like got a really good deal on your 11 with 80k.
Since it is certified I am under the impression only vehicles with clean car fax history can be certified. So assuming the condition is good.
In the past 90 days I sold one of my 200s the one that had 57k miles. I sold it to s local Chevy dealer for $40k in January, they sent it to an auction in Texas in Feb, where it sold for $43k, it then turned up at a dealer in KY listed for sale at $48k .
With shipping and auction fees the dealer that has it now likely has around $45k invested in it.
So having just watched all that happen with one of my 2011 model 200's this year, I really believe $38k was really good deal for you.
Something I have seen over the past 7 or 8 years with having owned 4 different 200s in that time, is that there are so few imported to the US market, that when dealers are trying to access their value, they seem to be all over the place. On the last one I had dealer buy bid offers were ranging from 34k-40k, and eventually seen with the dealer that has it now, he stepped up to likely $45k all in. That's a $10k spread between various dealers opinions of what that same 200 was worth.
I have also noticed when shopping for them, that there seems to be hot spots around the US where you find quite a few to pic from , and other parts where there won't be a single one for sale in a several hundred mile radius.
