By contrast, the CT5 offers a lot more value in the mid-$40,000 range, without too many compromises.
The Lexus ES is priced like the CT5 but skews strongly toward luxury.
The Volvo S90 is a spacious, understated sedan that offers so much style but is no match for the Cadillac when it comes to agility.
