Full-size Sedan · what it costs new, what it’s worth used, and who has one near you.
The 2018 Cadillac CT6 is a full-size sedan we track across the used market in Canada. It comes in gas (13.8 L/100 km) and hybrid (9.2 L/100 km) forms, so the main choice is fuel — the hybrid earns its premium back over enough kilometres. A 3-year-old one keeps roughly 45% of a current model's market price — what actually matters over five years of ownership.
