However, realizing that this is a modern engine and some of them are known to produce an over-abundance of sludge and varnish. I was wondering if anyone has any experience with that GM engine and whether it is durable or not?? Is it a sludger?? Any advice, thoughts, or good maintenance tricks would be greatly appreciated. Thanks.

Your "BOLD" statement concerned me as I have never read this before. Judging by the rest of the replies here, I'd say the info is false, at least with the newer models.
We purchased ours last November 17 and couldn't be happier! It has been an excellent car so far and trouble free with around 26,000 kms on it (We purchased it used with around 20k)
I have been using my favorite oil of choice in PUP 5W-30 and haven't noticed any oil consumption despite my wife only doing short city driving mainly of around 20 kms per day.
Great choice of color, by the way!

I just finished waxing it within the last couple of weeks using Collinite 845 Insulator wax. Great wax and it sure makes it shine!
