CadillacBuying a luxury SUV doesn't necessarily mean spending luxury money, especially if you're willing to look at a lightly used model. Depreciation can turn once-expensive premium SUVs into surprisingly affordable alternatives to new mainstream crossovers, but reliability is often the catch. Fortunately, one American luxury SUV bucks that trend, offering a comfortable, well-equipped cabin and a stronger reputation for dependability than you might expect.Three-year-old examples can now be found for less than many new mainstream SUVs, making this an especially tempting option for budget-conscious buyers who still want a more upscale driving experience. It isn't the sportiest or most luxurious SUV in its class, but it delivers plenty of space, modern technology, and everyday comfort without the eye-watering price tag or questionable reliability that can come with some used luxury vehicles.In order to give you the most up-to-date and accurate information possible, the data used to compile this article was sourced from various manufacturer websites and other authorities, including the EPA, CarEdge, J.D. Power, and Edmunds.The 2023 Cadillac XT4 is a sturdy luxury SUV that won't break the bankCheaper than a new RAV4 and just as reliableAmerican luxury SUVs usually beat their foreign rivals in terms of value for money, even when brand new. Thanks to steady depreciation, lightly used models offer quite a lot of bang-for-your-buck. Unfortunately, American automakers aren't exactly known for their dependability. However, the 2023 Cadillac XT4 exceeds expectations, with a strong track record when it comes to reliability, and an interior loaded with luxury, all at a price that is hard to pass up.A plush luxury SUV for the price of a mainstream sedanThe XT4 might not be the most popular choice, but it's one that offers quite a lot of value for money. It was one of the cheaper options in its segment when new, starting at $37,490 and going up to $41,990 for the most expensive trim. Because of the negative misconceptions around American automakers, the XT4 has depreciated pretty aggressively in its first three years and can now be had for the price of a midsize sedan.AdvertisementAdvertisementWe think that most people will find the Premium Luxury trim the most satisfying. It builds on the strong list of standard features without costing much more than the base model. You get things like heated front seats, a power-adjustable driver's seat with a memory function, ambient interior lighting, and leather upholstery.A strong track record for reliabilityReliability score: 85/100 (J.D. Power)Average 10-year maintenance costs: $12,813 (CarEdge)Many don't know this, but many authorities consider Cadillac to be one of the more reliable brands on the market. J.D. Power, for instance, found that they were the second most reliable luxury brand on the market in 2026, coming second only to Lexus. The XT4 has consistently ranked as one of their more reliable models.CarEdge also estimates that the XT4's maintenance costs, in the long run, are lower than average for its segment.Cadillac delivers a simple but comfortable interior in the XT4You get all the modern features you could wantWhile the XT4 might not be the outright plushest option in its segment, it is also generally a lot cheaper than most of its core rivals. It strikes a really good balance between interior luxury and affordability. Cadillac doesn't skimp on tech features either, with all the modern amenities you could possibly want coming standard.More spacious than German alternativesThe XT4 is impressively practical for a small crossover. Compared to other options in its class, it has one of the most spacious rear seats that you can get. There is loads of legroom up front and in the back, and you're not likely to hear any complaints about space, even from taller passengers. Room in the trunk isn't mind-blowing, but it is more than enough for the average buyer.AdvertisementAdvertisementGenerally, the build quality in the XT4 is good, and there are some nice materials used throughout. There are, however, some touchpoints where you'll find low-rent plastic, but we don't think this is a deal breaker, especially at this price. Top trims also come with some nice luxuries, including things like power-adjustable front seats with a memory function, leather upholstery, ambient interior lighting, and carbon fiber or wood trim.Infotainment and technologyEvery model comes equipped with the same eight-inch infotainment screen. It sits slightly embedded into the dashboard. It is crisp and responds quickly to inputs. As well as using touch inputs, you can control the system via a rotary knob on the center console. We also really appreciate that there are plenty of physical shortcut buttons.Apple CarPlay and Android Auto are both standard on every model, as is on-board Wi-Fi and a seven-speaker sound system. We'd look for a model equipped with the Technology package as well, which adds a heads-up display, wireless smartphone charging pad, and a digital gauge cluster. A 13-speaker Bose sound system is also optional.Cadillac focuses more on comfort than sportinessThe XT4 isn't exactly an athleteCadillacWhere other luxury automakers try to mix some sportiness into their small SUVs, Cadillac's XT4 is more of a casual cruiser. We don't think that's a bad thing, though. For those that prioritize quiet comfort over athleticism and silly zero to 60 times, the Cadillac's driving experience is more than adequate.Enough pep for most buyersEvery model comes equipped with a turbocharged four-pot under the hood. It sends power to the front-wheels as standard through a nine-speed automatic transmission. All-wheel drive is optional, though. Compared to other luxury crossovers, acceleration is pretty lackluster, but compared to new cars at this price point, the XT4 is more than quick enough.AdvertisementAdvertisementCadillac's small SUV isn't particularly sporty. Everything, from the steering to the suspension, is soft. Despite its name, even the Sport model doesn't feel particularly exciting. The ride quality is pretty decent, though some bumps and jolts do make their way into the cabin.Instead of a mainstream sedan, you can get this used luxury SUVBuying a used luxury car is usually a bit of a gamble, with reliability being a major concern. Despite coming from an American automaker, the XT4 quells those worries, with a track record for dependability that would make Japanese brands blush. With depreciation being on your side, it can also be had for an extremely reasonable price, meaning that you can ride around in style without breaking your bank account.
