2023 Lincoln CorsairLincoln can't call itself the oldest American car brand, but it can still trace its roots all the way back to 1917. Lincoln has since developed into one of the most prominent nameplates in the luxury segment, with its current fleet retaining its legacy exclusively within the SUV segment. You still have the choice of models like the long-standing Navigator, but the smallest SUV, the Corsair, was only introduced for the 2020 model year, and certainly shouldn't be overlooked.The 2025 Lincoln Corsair is notably cheaper than the three other SUVs from the brand, with a starting price of $39,485. However, if you go back only two years, the 2023 Corsair can be bought on the used market for an average price of $29,617, according to KBB. While other Lincoln models see improvements this year, the Corsair only received its first refresh with the 2023 model, which still carries over into 2025.The 2023 model introduced plenty of new features for the compact luxury SUV to further separate it from its key European rivals, with the hands-free advanced driving assist system bringing significant advances to the ultra-competitive segment. This Corsair also has a 13.2-inch center touchscreen and the 12.3-inch digital gauge cluster, as well as a few design updates to the front fascia. Then there's the current model's 2.0L turbocharged four-cylinder engine producing 250 horsepower and 275 pound-feet of torque, all for under $30,000.2022 Mercedes-Benz CLAKeeping on topic with Mercedes-Benz, there's also no shortage of options to choose from the legendary automaker. Mercedes-Benz can trace its roots in the luxury segment further back than the likes of BMW, with the Daimler Motor Car released in 1892, and the standard set over 100 years ago is still present today, with the CLA Coupe being one of the entry-level models currently offered.The CLA starts at $42,750, a price tag sure to turn heads. However, if you're looking for the ultimate levels of luxury on a relative budget, the 2022 CLA Coupe comes in at just $29,430 for the base trim, as per KBB. The coupe received a major update for the 2020 model year that has lasted until this year, with some changes that haven't made a huge difference since then. Under the hood of the 2022 Mercedes-Benz CLA is a 2.0L four-cylinder engine producing 221 horsepower and 258 pound-feet of torque, the same as what you get in the 2025 model. A 48-volt mild hybrid system was introduced in 2024, but the power output wasn't affected, and the fuel efficiency only improved by 1 MPG to 30 MPG combined.2022 Acura TLXAnother luxury division of a major Japanese automaker, Acura falls under Honda's wing but in a more unique way than Lexus does to Toyota. While Lexus models are sold internationally, Acura channels most of its focus to the U.S. market. While Honda has a much more expansive range of affordable vehicles to appeal to the widest market possible, Acura only produces six vehicles in total, but manages to cover decent ground with its relatively limited lineup. Only introduced in 2014, the mid-size TLX sedan is designed to blend luxury with speed; a combination worthy of a $45,400 price tag.The TLX's current MSRP keeps it competitively priced within the mid-sized luxury segment, but the 2022 model can save you a solid amount of money and bring the price under $30,000. For the base 2022 TLX 2.0, KBB reports a national average price of $27,941, with the all-wheel-drive model going for $28,927 and the base trim with the technology package slightly increasing the price tag to an average of $28,827.In 2024, Acura gave the TLX a refresh that included an updated front fascia as well as a bigger center touchscreen display, going from 10.2 inches to 12.3 inches. Despite these changes, the entry-level TLX, now called the Technology trim, still uses the same 2.0L turbocharged four-cylinder engine producing 272 horsepower and 280 pound-feet of torque, which is still impressive three years down the line.2023 Cadillac XT5Shifting focus back to Cadillac and its fleet of SUVs, the XT5 finds itself in the middle of the XT lineup, between the XT4 and XT6. Despite the American Automaker putting a lot of effort into its electrified SUVs, even if the brand's all-electric goal by 2030 is no longer moving forward as planned, the mid-size XT5 is still in the mix with the best of its class at a price tag of $44,800 for the 2026 model. Due to this, despite still being a brand-new model available for purchase, the XT5 hasn't received a major refresh since 2020, instead receiving various smaller updates over the years.To stay under the $30,000, the latest XT5 model you can look at buying on the used market is the 2023 model, which can be picked up for an average price of $28,670 in its base Luxury guise, according to KBB. Underpinning this trim is the 2.0L turbocharged four-cylinder engine producing a solid 235 horsepower and 258 pound-feet of torque. The 2023 XT5 also has a more potent 3.6L V6 engine that comes with the Sport trim, but you'll have to pay $35,535 on average for the top-spec model. Inside, the key cabin technology is also the same as the 2026 model, with an 8-inch center display coming with features such as wireless Apple CarPlay and Android Auto, which were introduced in the 2021 model.
