Advice needed on potential purchase?
I am considering buying a 2017 CPO AMG GT with about 20k miles. I am pretty comfortable with buying due to CPO but other than reviewing service records is there anything, in particular, I should know that any of you wish you did before pulling the trigger?
Thanks,

Why a GT and not a GTS or a GTR from the same era?

One thing I always do is to check the inside of the tailpipe(s) for black exhaust soot by running your finger around the inside of the pipe (or, in the case of most AMGs, the flange surrounding the tailpipe). My theory is that engines that are not broken in properly will exhibit more blow-by which can be detected by black soot in the exhaust system. It's true that a through wash job could remove any such soot, it's unlikely that was the case. While I only have anecdotal evidence that this theory/test is of any value, it can't hurt. If the car does have a lot of soot deposit, ask for a compression test to be run (not a small job on these engines).

Also, have the dealer do a fresh service along with a new safety check which will include remaining brake pad and tire thickness.
All of the fluids should be changed…transmission including a service, rear end, oil and ALL of the filters.
Good Luck.

It is nearly impossible to judge the condition of an engine by tail pipe color in this day and age.
Back in the day, when gas still had lead in it and there were not nearly the amount of cleaning additives added you could look for that light grey/tan tail pipe color. Same with the plugs--- very difficult to read plugs now.
