I grew up in the Chevy line up. My dad's first 5 cars were the Impala line up. I took my driving test with a 1977 Impala. Chevy added models with more features, but never flip flopped them. A 2014-15 ES is the 2017+ SE. That would be like saying the Bel Air has more features than an Impala or the Bel Air in now the Impala level & the Impala is the base model, which never happened. Yes, Bel Air was dropped eventually.
