If you’re in the market for a used Cadillac and want something that sits in the “Goldilocks zone” for size, then consider the XT5. Edmunds has noted that the XT5’s “second row will feel roomy to normal-sized adults, with plenty of knee- and legroom”. Being that it's not as big as some of the other vehicles in Cadillac's catalogue, this is the perfect size for those who value comfort. While it’s not perfect, it is close. These are some known issues in the Cadillac XT5 model.
