How much does the 2015 Cadillac ATS cost?

Prices are up 1.51% year-over-year — a sign of continued demand for this model year.

There are 341 listings available, which suggests a reasonably active market for shoppers comparing options. If you find a listing below $10,684.79, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2015 Cadillac ATS a good car?

Yes — the 5/5 user rating points to strong owner satisfaction, and the expert score is 5.67/10. The model scores 9/10 across Look and feel and Performance.

The overview frames this ATS as a compact luxury sedan that reflects Cadillac’s push to sharpen its engineering, design, and materials, with a more distinctive personality than a typical commuter sedan. The expert notes reinforce that impression: the car is rewarding to drive, polished in execution, and aimed at buyers who want something that feels like a statement as much as daily transportation.

The market also shows 29.3% of listings as good or great deals, which gives you some room to shop selectively.

Is the 2015 Cadillac ATS reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The expert notes describe a car that is phenomenal from a mechanical engineering and driving-dynamics standpoint, but they also point to a premium-car ownership experience that can be frustrating if you value simplicity and broad value. The performance write-up favors the available V6 for refinement, while the cost-effectiveness notes suggest the ATS asks a lot from buyers in exchange for its driving appeal.

For used buyers, the main long-term risk is that a well-equipped ATS can be expensive to live with if you want strong features, easy-to-use tech, and a more forgiving ownership experience.

What should I look for when buying a used 2015 Cadillac ATS?

At 54% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if the car has had multiple owners or any bodywork. Focus on condition, equipment completeness, and whether the car’s premium features still work as intended, since this model’s appeal depends heavily on how well it was maintained.

Key things to evaluate:

• Trim level: The base setup lacks some of the features that make the ATS feel properly premium, and the safety equipment is not fully standard until you move up the lineup.
• Powertrain: The base 4-cylinder is the entry point, while the optional turbocharged 2.0-liter 4-cylinder and available 3.6-liter V6 are the stronger choices; the 2.0-liter returns 24 mpg in combined driving.
• Safety package: Forward-collision warning is easy to get, but lane-departure warning and lane-keeping assist require a higher collection plus the Safety and Security package; blind-spot monitoring is limited to higher collections and bundled with other equipment.
• Infotainment: The CUE system is touch-based and can be frustrating to use, with voice recognition that does not seem especially responsive.
• Fuel efficiency: The turbocharged 2.0-liter 4-cylinder is rated at 24 mpg combined, and the expert averaged 22.9 mpg with a heavy right foot.

Which 2015 Cadillac ATS trim should I buy?

The 2015 Cadillac ATS is offered in 3 trim levels: Standard collection, Luxury collection, Performance collection.

Here's the short version:

• Base trim: The Standard collection is the least expensive path in, but it misses some of the features that make the ATS feel fully realized, and key safety content requires stepping up.
• Sweet-spot trim: The Performance collection is the best all-around choice if you want the strongest mix of safety content and driving appeal without going all the way to the most expensive setup.
• Premium/top trim: The Premium collection adds the most upscale feel, and it is the trim where the car’s materials and available performance hardware make the biggest impression.

The safety-package note is simple: forward-collision warning is easy to get, while lane-departure warning, lane-keeping assist, and blind-spot monitoring are tied to higher collections and bundled options.

Is now a good time to buy a used 2015 Cadillac ATS?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find value if you compare condition closely.

• Deal availability: 29.3% of listings are priced as good or great deals.
• Inventory: There are 341 listings available.
• Price trend: Prices are up 1.51% year-over-year.
• Clean inventory: 54.0% of listings are accident-free.

If you find a listing below $10,684.79, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2015 Cadillac ATS's resale value?

The current average of $11,069 sits slightly above last year's $10,905.

That modest increase suggests the market has held up reasonably well for this model year, even if it is not showing dramatic appreciation. For a future seller, that means condition and equipment will matter a lot: a cleaner, better-equipped ATS should be easier to position than one with accident history or missing premium features.

The price trend also suggests buyers are still willing to pay for the ATS’s driving character and upscale presentation, which helps support demand. If you maintain the car well and keep it in strong cosmetic and mechanical shape, you should have a better shot at preserving value.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2015 Cadillac ATS safe?

It earns five-star ratings in every assessment the NHTSA conducts on new cars, including for rollover resistance.

It earns a 5/10 safety score from our experts.

Cadillac makes forward-collision warning relatively easy to get, but lane-departure warning and lane-keeping assist require a higher collection plus the Safety and Security package. Blind-spot monitoring is limited to the Performance and Premium collections and is bundled with other equipment, so you may need to shop carefully if that feature matters to you.

Should I buy a 2015 Cadillac ATS or consider a different year?

If you're weighing the 2015 against nearby model years, here's how to think about it:

Choose the 2015 if:

• 29.3% of listings are priced as good or great deals.
• At 54% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 1.51% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2015 ATS is praised for its sharp driving dynamics and polished design.

Consider the 2016 if:

• At $12,221, the 2016 costs more than the current year's $11,069 average.
• It adds a more potent V6 and Apple CarPlay.

The bottom line: If you want the lower entry price and the core ATS driving experience, the 2015 is the better value. If you are willing to spend more for a newer version with a stronger engine and better infotainment, the 2016 is the smarter upgrade. For price-sensitive buyers, the 2015 remains the more approachable way into this sedan.
