TCC’s Bottom Line

The 2018 Buick LaCrosse is a proper flagship, a refined and comfortable sedan with only a few quirks.

The 2018 Kia K900 is a premium, luxury sedan without much of an identity.

TCC Likes

Elegant styling inside and out
Good infotainment system
Silent cruiser

Relative value compared to some
Big back seat
Whisper-quiet ride

TCC Dislikes

Advanced safety tech is pricey
Odd trim level walk
Not as roomy inside as its size would suggest

…but may put some to sleep
Poor fuel economy
Lacking some safety tech
