Would it be a bad idea to buy a 2020 Cadillac XT6 Premium Luxury Sport Utility 4D with 51,000 for $27,000?

Hi. I am in the market for an SUV and have been having trouble deciding between a couple of different vehicles. As I mentioned, I have come across a 2020 Cadillac XT6 Premium Luxury Sport Utility 4D with 51,000 miles for $27,000? I really like the safety/driver assistance features it has and I want a vehicle that has a really quiet and comfortable cabin/ride. What would I need to be looking for or aware of regarding this vehicle? The price is a little bit higher than I had planned on spending but would be willing if its worth it.
