The Car Connection's Take

TCC Rating

7.2

TCC’s Bottom Line
The 2018 Buick LaCrosse is a proper flagship, a refined and comfortable sedan with only a few quirks. The 2018 Chevrolet Impala adds better base equipment this year for good value among full-sizers. The 2018 Toyota Avalon is a spacious full-size sedan that prioritizes comfort and safety above keeping up with the Joneses.
