2017 Cadillac CT6
2.0T Luxury RWD
101,663 mi
$14,794
Overview
The “Cadillac of Cadillacs,” the CT6 serves as the brand’s new flagship—and its first genuinely competitive large luxury sedan in decades.
Unlike the last handful of Cadillac range-toppers, the CT6 shares little with the rest of parent company General Motors’ other models. Instead, it utilizes its own highly advanced aluminum structure underneath its angular, svelte styling.
The CT6 may look relatively small thanks to its short overhangs and trim details, but the sedan stretches 204 inches from head to toe. That puts it somewhere between rivals like the BMW 5 Series and 7 Series. But despite that size disparity, the CT6 is priced and powered more like the smaller 5 Series.
Thanks to the extensive use of aluminum and other weight-saving materials, the CT6 weighs less than the 5 Series despite offering considerably more interior and cargo volume. That light weight also makes it especially lithe on its feet for such a large 4-door, and it means its power-to-weight ratio is decidedly advantageous over that of its rivals.
To that end, the CT6 offers a trio of engine choices: A 2.0-liter turbocharged 4-cylinder, a 3.6-liter V6, and a 3.0-liter twin-turbocharged V6. The base 2.0-liter variant can be paired with either rear- or all-wheel drive, while both V6 models exclusively send power to all four wheels—a boon for wintry weather markets.
The 2.0-liter is rated at 265 hp, while the 3.6-liter bumps that figure to 335. Fuel economy checks in at 22 mpg city/31 mpg highway/25 mpg combined for the 4-cylinder and 18/27/22 for the 3.6-liter V6.
But the real newsmaker is the top-of-the-line 3.0-liter twin-turbocharged engine, which delivers an impressive 404 hp. Thanks to the turbochargers, which allow more power to be extrapolated from a smaller engine, the 3.0-liter is rated at a decent 18/26/21. All told, that is a minor fuel-economy hit for a lot more power.
Making the most of that performance is a suspension designed with a decidedly European flair. Cadillac again looked to aluminum to help shave weight, but it is the company’s Magnetic Ride Control system that really helps the CT6 stand apart. Developed initially for the Chevrolet Corvette sports car and now utilized in a number of Ferraris, Magnetic Ride Control utilizes a high-tech fluid to help the suspension soak up bumps while retaining a degree of stiffness to keep the car flat and stable in corners.
Buyers looking for even more handling poise can opt for an available Active Chassis System that features rear-wheel steering. In short, the rear wheels are able to move slightly in order to reduce the car’s turning radius in urban areas and to balance its handling on wide, sweeping corners at higher speeds.
Befitting its luxury segment positioning, the CT6 offers a wide array of convenience and safety features.
Look in the CT6’s rear-view mirror and you’re actually looking at a high-resolution video captured by a camera mounted on the car’s trunk lid. The display allows for an unobstructed view behind the car, meaning drivers don’t have to look around rear seat passengers’ heads or thick roof pillars.
Speaking of screens, an enormous 10.4-inch capacitive touch display with a separate touchpad, like that on a laptop computer, serves as an interface for Cadillac’s CUE infotainment system. The system can read a user’s handwriting for faster navigational inputs. General Motors’ OnStar connectivity system comes standard on the CT6, with a concierge service, turn-by-turn directions, automatic collision notification, and a 4G LTE WiFi hotspot. Most of those features require a subscription that can get pricey after the free trial period runs out.
On the luxury front, all CT6s come well equipped, but the Platinum trim level pampers equally with heated, air-conditioned, and power-adjusted seats for every passenger.

Is the 2017 Cadillac CT6 reliable?
Owners rate it 4.69/5, a strong signal of long-term satisfaction.
The feedback points to a car that many owners feel good about living with over time, especially because drivers describe it as smooth, comfortable, and enjoyable to own. That said, used luxury cars can become more expensive to keep in top shape as they age, so you should pay close attention to maintenance history and overall condition.
What should I look for when buying a used 2017 Cadillac CT6?
At 60.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should start with a vehicle history report so you can confirm accident records, title status, and ownership history. After that, prioritize a thorough pre-purchase inspection, especially for signs of uneven wear, cosmetic repairs, or anything that suggests the car has been repaired after damage. Focus on overall condition and documentation, since a well-kept example is likely to be the better long-term buy.
Is now a good time to buy a used 2017 Cadillac CT6?
This looks like a moderate, selective buyer's market, so you can shop carefully and still find opportunities.
- Deal availability: 29.4% of listings are priced as good or great deals.

What is the 2017 Cadillac CT6's resale value?
The current average of $18,527 sits slightly below last year's $21,798.
That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For future resale, the softer current pricing may limit upside in the short term, but a well-kept example can still hold appeal if it stays clean and well documented. Strong condition and a good ownership record matter more when the market is already pricing in depreciation.
Vehicles with strong owner satisfaction ratings, like this model year's 4.69/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2017 Cadillac CT6 or consider a different year?
If you're weighing the 2017 against nearby model years, here's how to think about it:
Choose the 2017 if:
- 29.4% of listings are priced as good or great deals.
- At 60.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 15.00% compared with last year.
- Owners rate it 4.69/5 — a strong satisfaction signal.
The bottom line: If you want the best balance of value and owner satisfaction, the 2017 is a reasonable place to start, especially because prices have moved down and there are still some attractive deals in the market. If you're especially price-sensitive, you may want to compare nearby years and focus on the cleanest, best-documented example rather than chasing the lowest sticker price.
