Visited local dealer a couple days ago to check out the 2017 LaCrosse. He has four 2016 and one 2017 Cascadas in stock. All high line. The 2017 has BEAUTIFUL wheels. Much better looking than the 2016 wheels. The bad is that Blind Spot Warning still not offered.
Also noticed that the 2017 LaCrosse (he has eleven of them) gets better gas mileage than the Cascada, even though the LaCrosse engine is over twice as large as the Cascada.
21-25-31 for the LaCrosse
20-23-27 for the Cascada
