The Buick Regal is a multi-decade nameplate introduced in 1973, but its engines, trims, body styles, and drivetrains vary substantially by model year and market. In North America, the lineup changed from earlier coupe and sedan offerings to the Sportback liftback and TourX wagon for 2018, and ended after the 2020 model year.
For a used Regal, verify the exact year, trim, body style, engine, drivetrain, equipment, and condition rather than assuming specifications carry across generations. The examples below are tied to their cited model years; they are not a complete year-by-year specification history.
Buick Regal generations and major changes
Cars.com identifies 1973 as the Regal’s introduction, as an upscale version of Buick’s mid-size Century. The nameplate later became associated with performance variants including the 1987 GNX, which appears in GM’s Heritage Collection. The available research does not establish a complete authoritative chronology of every generation and trim, so specific details should be checked against the relevant model-year material.
| Model-year phase | What the sources establish | Buyer note |
|---|---|---|
| 1973 introduction | Cars.com describes the Regal as an upscale version of the mid-size Century. | Do not infer exact engine or trim specifications without a year-specific source. |
| 1987 GNX | GM’s Heritage Collection includes an entry for the 1987 Buick Regal GNX. | Its presence documents the model’s performance heritage; consult vehicle-specific records for detailed specifications and condition. |
| 2017 | Kelley Blue Book lists a 2.4L four-cylinder on the base 1SV front-wheel-drive sedan and a 2.0L turbo four-cylinder on other trims; a six-speed automatic is listed across the line, with AWD on selected trims. | Engine and drivetrain depend on trim. Check the exact car and its original equipment. |
| 2018 redesign | Cars.com describes two body styles: the Regal Sportback and Regal TourX wagon. The Sportback has a liftback-like shape. | Compare the liftback and wagon as distinct body styles, not as interchangeable trims. |
| 2020 | The NHTSA-hosted GM VIN reference maps Regal engine codes to a 2.0L turbo four-cylinder and 3.6L V6, and includes series labels such as Preferred, Essence, GS, and Avenir. | VIN series labels are not a complete retail configuration list. Verify the specific market and model-year catalog. |
| After 2020 | Cars.com says the Sportback and TourX were discontinued after model year 2020. | This is the end of the North American lineup described by the source, not necessarily every global-market use of the Regal name. |
Buick Regal engine options and specs
Regal specifications are model-year-specific. Kelley Blue Book’s 2017 model information lists 182 horsepower for the 2.4L four-cylinder and 259 horsepower for the 2.0L turbo. Those figures describe 2017 configurations; they should not be applied to every Regal or to later Sportback and TourX models.

Regal Sportback vs. TourX
For the 2018 redesign, Buick offered two distinct body styles. Cars.com characterizes the Sportback as a coupé-shaped, liftback-like design with more cargo room than a typical sedan, while the TourX is a wagon. The body style affects practicality and should be part of any comparison.

- 1974 - 1987 Buick Mid-Size RWD Models Haynes Repair Manual + Free Gloves
| Body style | Basic distinction | What to verify |
|---|---|---|
| Regal Sportback | Liftback-like profile with a rear opening for cargo access. | Exact model year, trim, engine, drivetrain, and equipment. |
| Regal TourX | Wagon body style. | Exact model year, trim, engine, drivetrain, and equipment. |
Cars.com describes the Sportback GS as using a 310-hp V6. Confirm the precise year and configuration in the applicable model-year catalog before relying on that specification.
How much is a used Buick Regal worth?
Used Regal value depends on model year, trim, mileage, condition, location, and sale channel; there is no single reliable price for every generation. As a dated reference, Kelley Blue Book displayed national-average fair purchase prices of $10,350 for the 2017 1SV Sedan and $13,200 for the 2017 GS Sedan, valid through October 6, 2026. These are typical-condition dealer-purchase estimates, not an appraisal or guaranteed transaction price.

Kelley Blue Book says its estimates vary with mileage, condition, location, and other factors. Its 2013 model page also provides trim-level estimates, but those should likewise be treated as model- and condition-specific. Collectible examples such as the GNX need an individual assessment based on condition, provenance, and the market; the available research does not support a universal all-generation value range.
How to compare used Buick Regals
- Identify the exact model year, market, body style, trim, and VIN.
- Confirm the engine, transmission, and drivetrain for that specific configuration using year-specific documentation.
- Compare equipment using the contemporaneous Buick brochure or catalog; trim names and features can vary by year.
- Assess the individual vehicle’s condition, mileage, title and history, and location.
- Compare current local listings and valuation estimates, noting the estimate’s date and assumptions.
