Read recent reviews for the Cadillac XT6
XT6
Kyle, 10/12/2020
2020 Cadillac XT6 Sport 4dr SUV AWD (3.6L 6cyl 9A)
My wife has driven a full size XL version of Suburban or Yukon for the past 20 years. With the kids out of the house now, it was time to go a little smaller and sporty. The XT6 Sport model fit the bill. The wife loves it and we didn’t really give up much cargo space.
Spend the money and go with the AWD or AWD Sport model. We teat drove the FWD and there is no comparison.
