TCC’s Bottom Line
A nip and tuck for this year isn't enough to ignore the wrinkles in the aging 2018 Infiniti QX80. The 2018 Lincoln Navigator takes such massive doses of swagger, you’ll swear it’s 1998 all over again. The 2018 Mercedes-Benz GLS takes an old-school tack to modern-SUV design, and it works.
