Just as an FYI on the Trim Packages ...
2012 had 3 trim levels. Base, Convenience, and Leather. The 2.0L Turbo was not available.
2013 added the Premium Turbo Group with the 2.0L Turbo.
2014 same as 2013
2015 added the 1SV trim group that was actually "below" the Base Group.
2016 replaced the Convenience Group with the Sport Touring Group - Appears to be mechanically the same as the previous Convenience Group.
2017 dropped the 1SV and Premium Turbo trim levels. The remaining trim levels remained the same.
Yeah....? Not sure how Buick could call it "Sport Touring" without it having the 2.0L Turbo and the slightly stiffer suspension offered on the Premium Trim Level. IMO - Just marketing sales ploy.
I have a 2013 Premium Turbo, and I REALLY REALLY like the 2.0L Turbo. 250hp v/s 180hp in the 2.4L
I also have the optional 18" Forged Alloy wheels which I believe have a lower profile tire than the standard 17".
Even with the low profile tires, I personally do not find the ride to be harsh or stiff at all.
And the handling is actually "just right" for a vehicle in this class and price range.
