I haven't found actual conformation from Buick/GM, but this site says 18x8, 40 offset, and 5x115 bolt pattern:

I agree with you about the OEM wheels. Even the higher trim levels of this car still come with the same frumpy ones. I plan on changing mine over when the stock tires wear down.

The specs BrianCoasters posted are correct. My winter wheels have a larger centerbore so I used some hub centric rings to snug them up perfectly.
I almost like the styling of my winter wheels more than the factory wheels...

I've been researching a bit. It looks like the Lacrosse wheels are the same size/bolt pattern/offset. Kinda liking these.
Also this Verano wheel is the same but the offset is 46 not 40mm. I'm guessing 6mm would be noticable? I like the Verano better.

I love the factory wheels!
That's 1/4". Is that positive or negative offset?
More negative might look good, because it would push the wheels/tires further out. More positive would look stupid and might cause rubbing, but could be fixed with spacers.

Looking at some 20" Lacrosse wheels. The wheels are larger but the sidewall is less so the total extra diameter is only +.4". I understand the Buick ride height was raised a half an inch so there should be room in the wheel well. Will this affect any of the stability/TC electronics?

No, anti-lock, stability, traction control are all non-issues.
Look at the weight, though. Plus-sizing rims usually means dramatically more weight.

You sound like my TDI-brethren looking for maximum fuel economy by being conscious of rotational mass. 
Joking aside this is a valid point. Even these alloys get quite heavy, and the tires too.

People usually assume that bigger wheels/shorter tires ride badly because there's not enough sidewall compliance, but a lot of that is the greater unsprung weight.

The baddest wagons I ever owned were all three of the 149 1991 Audi 200 Turbo Quattro Wagons that were imported into the US. Only available with 5 speeds and loaded (for their day) with the only choices being exterior and interior color and "Sport" or "Comfort" seats in the front. Car and Driver said that if Lamborghini made a wagon, this would be it. Audi was still recovering in the US at the time and these came in at a cool $41K in 1991. There just wasn't a lot of demand for speedy wagons with sticks, turbos, and sodium filled valves at over $40g's at the time (about $77K adjusted for 2018). One unique feature were the ultra light 15 inch BBS factory wheels which were there to reduce unsprung weight but that also carried a "comfortable" sidewall for that "Oh so lovely ride." In order to get sufficient braking the calipers were installed around the center of the brake rotors which were "affectionately" known as UFO's for their odd looking design. Unfortunately, if you can find them, a set of these rotors (two) will run you a cool grand or more and parts for these cars are so hard to find I finally gave up my last 200TQW a couple of months ago. Here's a quick tutorial on some automotive history.... and a photo of my last one, not a bad looking rig for a 27 year old car. It would pull sub 15 sec quarter miles at my local drag strip on street nights without even beating on it, although it was chipped (chip by a company called "Intended Acceleration" ;-) ) Also, as an aside, a used set of these rotors make an excellent mooring for a 17' Glastron in fresh water.

Interesting article. Too bad C&D didn't post the weights of each to see the change as you increase, or how performance was affected. Curious how the ride/handling sweet spot was 2" to 3" bigger than stock. Although a 15" wheel is rather small by today's standards.

They did, and there were tables of all the data, but somehow C&D isn't hosting the tables anymore...
I think it's simply an 8-year-old story, and all the images were discarded at some point...
