Which car would be better choice? 2017 Buick Lacrosse or 2019 Buick Regal sport back AWD?

Hey guys,

I am looking at these two options right now. Both cars have about the same mileage (62K) and dealer is asking the same price (12K$). I had a 2011 Buick lacrosse couple of years ago and I liked the comfort seats and the quality of the car except the gas consumption which was weirdly high. After driving a Subaru outback for almost 5 years, I decided to give the Buick another chance as we need a second car for the family. Which one would be better in terms of reliability and maintenance? Should I be worry about parts availability as both of those models are discontinued ?
