Is the 2016 Cadillac CT6 a Good Used Car?

The inaugural Cadillac CT6 is a good used car. It hits all the marks for an upscale sedan, like a top-notch interior, comfortable seats, and more features than you can shake a stick at.

How Much Does the 2016 Cadillac CT6 Cost to Own?

The 2016 CT6 sedan tends to have more affordable fuel, insurance, repair, and maintenance costs than some of its competitors. You can expect to pay around $28,200 over five years for these expenses. By comparison, these five-year costs for a 2016 BMW 5 Series are about $4,600 higher, while the 2016 Audi A7 will likely cost you around $3,200 more than the CT6. However, a 2016 Cadillac XTS will likely save you about $1,300 in five-year costs.

Is It Better to Buy a Used or New CT6?

Cadillac introduced its Super Cruise technology as an option in the 2018 CT6. This Level 2 autonomous driving system controls the car's speed, braking, and steering without you having to touch the wheel. It monitors your eye movements to ensure that you're still paying attention to the road. The system works only on the 130,000 miles of limited-access highways that Cadillac has mapped out across the country. If you want to be on the cutting-edge of self-driving technology, a new 2018 Cadillac CT6 is one of your best options. However, you'll have to pay for it – a model with Super Cruise starts at about $70,000. With the average price of a used 2016 CT6 at around $53,000, you'll have to decide if that price increase is worth these cool autonomous capabilities.

As of this writing, one recall applies to the 2016 Cadillac CT6. It addresses a missing bolt that can allow the front passenger seatbelt webbing to detach, increasing the risk of injury in the result of an accident. Before purchasing a used CT6, make sure this issue has been dealt with.

Which Model Year of the Cadillac CT6 Is Best?

The CT6 sedan was introduced as an all-new vehicle for the 2016 model year, and there have been few major changes since then. A plug-in hybrid variant debuted as a late-model 2017, with an all-electric range of 31 miles and good fuel economy (62 combined mpg-e). Average prices of  2016 and 2017 CT6 models are very similar, so don’t limit your search to one model year.

Which Used Cadillac CT6 Model Is Right for Me?

The 2016 CT6 comes in four different trim levels: base, Luxury, Premium Luxury, and Platinum. While the base and Luxury trims offer a decent amount of features, the Premium Luxury and Platinum trims are worth the extra splurging on. The top-level Platinum trim has tons of luxurious interior upgrades, like a 34-speaker Bose Panaray sound system and a rear-seat Blu-ray entertainment system with two 10-inch HD screens. Up front, travelers enjoy massaging seats with heat and ventilation. The quad-zone automatic climate control system eliminates squabbles over the air conditioning.

If you find that Platinum models are outside your price range, consider the Premium Luxury trim. It still comes packed with goodies but likely costs much less. Both the Premium Luxury and Platinum models feature the 335-horsepower V6 engine and all-wheel drive. The Premium Luxury trims comes with a head-up display, a panoramic sunroof, and a rear camera mirror, which gives you a streaming video feed in place of a traditional mirror for increased visibility.

What Does Cadillac's Certified Pre-Owned Warranty Cover?

Cadillac offers a certified pre-owned program for vehicles four years old or less and with fewer than 50,000 miles. Eligibility is determined by the vehicle’s initial sale date. Qualifying vehicles see the original new-car limited warranty extended to six years or 100,000 miles. Cadillac CPO models must pass a 172-point inspection. Additional benefits like towing and roadside assistance may be available, so read Cadillac’s warranty page carefully.

Cadillac’s CPO program is OK, according to our analysis, but several luxury carmakers offer better programs. These include Lexus, Infiniti, Audi, and Acura.

2016 Cadillac CT6 Versus the Competition

Which Is Better: 2016 Cadillac CT6 or 2016 BMW 5 Series?

The 2016 BMW 5 Series is a luxury midsize car (smaller size class), but you won't sacrifice that much space compared to the CT6. The 5 Series has plenty of rear-seat room, but it lacks the CT6’s available second-row luxury features. Like most BMW models, the 5 Series offers many configurations, with a half a dozen engine options, including diesel and hybrid powertrains. The 5 Series sedan has less cargo space than the CT6, but the hatchback 5 Series Gran Turismo gives you much more utility than the Caddy. Both cars have comfortable, composed handling that makes them both fun to drive. Your choice may come down to price – the 5 Series has a lower average price than the CT6 by more than $10,000.

Which Is Better: 2016 Cadillac CT6 or 2016 Audi A7?

The 2016 Audi A7 has a below-average reliability rating and high ownership costs, which results in its low class ranking. However, it has good performance for the class, thanks to a standard supercharged V6 engine and all-wheel drive. The A7 has sharp cornering abilities, and available high-performance S7 and RS7 models are even sportier. The CT6 has equally laudable performance, so those looking for an engaging drive should approve of either model. The A7's fastback design gives it a lot more cargo space than the CT6. However, that design also takes away from headroom for rear-seat passengers. Both the A7 and the CT6 have elegant cabin materials and plenty of standard and available features. Most shoppers will likely be satisfied with either of these cars.

Which Is Better: 2016 Cadillac CT6 or 2016 Cadillac XTS?

The 2016 XTS is another luxury large car from Cadillac. While it ranks similarly to the CT6, the XTS has a different set of strengths. It has less athletic handling and a weaker base than the CT6. Both of these Caddies have nice interiors, but the CT6’s is more luxurious. It also offers some features that you won't find in an XTS. However, the XTS has great safety scores and will likely save you a bunch of money. The average price for the 2016 XTS is nearly half that of the 2016 CT6.

2016 CT6 Performance

How Does the 2016 Cadillac CT6 Drive?

The 2016 CT6 comes standard with a turbocharged four-cylinder engine that delivers plenty of power. If you crave more oomph, consider one of two available engines: a V6 with solid punch and a twin-turbocharged V6 that's downright potent. The CT6 is more agile than most classmates – with sharp steering and strong brakes – though it isn't quite as cushy as some rivals. The base engine is paired with rear-wheel drive, but both V6 engines come with all-wheel drive. Performance upgrades include Magnetic Ride Control, which is a rapidly adjusting suspension system.

Does the 2016 Cadillac CT6 Get Good Gas Mileage?

Fuel economy with the base engine is outstanding for such a large car, at 22 mpg in the city and 30 mpg on the highway. These estimates slip to 18 mpg in the city and 26 on the highway for the CT6 AWD with the largest engine.

2016 CT6 Interior

How Many People Does the 2016 CT6 Seat?

The Cadillac CT6 sedan seats five in a quiet cabin with extremely comfortable seats, top-notch materials, and streamlined styling. Leather upholstery, 14-way power-adjustable front seats, and dual-zone automatic climate control are among the standard delights that will keep you comfy. Other available features include upgraded leather upholstery, 16- or 20-way power-adjustable front seats, heated and ventilated front seats, and a heated steering wheel. Models with the Rear Seat package have a second row with 8-way power adjustment, as well as heating, cooling, massaging functions for the seats. The package also includes two 10-inch video displays and wireless headphones.

How Many Car Seats Fit in the 2016 Cadillac CT6?

The CT6 has two complete sets of LATCH child-seat connectors and a middle-seat tether anchor. Despite being located deep in the seat cushions, the lower LATCH anchors are easy to access. Upper tether anchors are also easy to use.

2016 Cadillac CT6 Features

The 2016 CT6’s standard features include a Bose eight-speaker audio system, three USB ports, Bluetooth, satellite radio, voice recognition, a 4G LTE Wi-Fi hot spot, wireless phone charging, Apple CarPlay, and Cadillac's CUE infotainment system. This system has a 10.2-inch touch screen and a console-mounted touchpad. Available features include navigation, a panoramic sunroof, quad-zone automatic climate control, a 12-inch gauge cluster screen, a 10-speaker Bose audio system, and a 34-speaker Bose Panaray audio system.

Although the infotainment interface is user-friendly overall, the system's touchpad controller can be awkward to use. There are also no redundant buttons or knobs to come to the rescue. Fortunately, you can circumvent the touch pad with the responsive touch screen.
