New-car prices have climbed to eye-watering levels, pushing more buyers toward the used market in search of value. As of August 2026, KBB reports that the average new car price has breached $50,000 – $50,089 to be precise. The good news is that the second-hand market is flush with compelling options — including genuine luxury cars that can be had for a fraction of their original sticker prices. The challenge, of course, is separating the bargains from the money pits: cars that look like deals on paper but quietly drain your wallet through repairs and maintenance.
If you know luxury cars, you know the terms ‘reliable’ and ‘affordable’ don’t mix well together. Although many luxury cars tend to fall victim to high depreciation rates, which result in them costing mere pennies on the dollar for second-hand buyers, more often than not this includes spending thousands in repairs and maintenance as well.
Fortunately, some of the most reliable cars ever made are luxury cars, and it all boils down to the fine details. Here are the most reliable luxury cars available today that don’t cost more than the average new car.
As mentioned previously, European luxury cars tend to depreciate at an alarming rate and cost an arm and a leg to maintain. Fortunately, the 2010 Audi A6, fitted with the supercharged 3.0-liter V-6, proves that reliable luxury cars exist. Its V-6 powerplant generates 300 horsepower and 310 pound-feet of torque — a cherry on top of an already compelling package.
Apart from having more than enough power, a used 2010 Audi A6 3.0 TFSI costs less than $10,000 on average. In turn, you won’t receive a ticking time bomb, but rather a well-built, reliable European luxury sedan.
The 2009 Infiniti G37 Sedan features a 3.7-liter V-6 engine making 328 horsepower, two fewer than the coupe’s V-6. So, why go for the lesser-powered sedan? Because it offers more cabin space than the coupe, translating to greater comfort for all occupants — and the four-door is cheaper to boot.
The G37 was much larger than its German competitors when it debuted — and significantly cheaper. Though it lacked the grace and driving dynamics of offerings like the BMW 3 Series, it offered affordable luxury. The G37 was a masterstroke from Infiniti, combining brisk performance, accessible luxury, and a generous standard-equipment list. You can get a good one today for under $8,000.
One car that you might have thought would never earn a spot on a list of reliable luxury cars is the Mercedes-Benz S-Class. Although unreliable S-Class models exist, the W221-generation S-Class is surprisingly dependable, especially the 2009 S550. Despite RepairPal giving the S550 a below-average reliability rating and claiming it costs nearly $1,500 per year to maintain, consumers tend to be satisfied with their ownership experience, as reflected in Edmunds’ consumer reports average rating of 4.8/5.0 stars for the 2009 S-Class.
Although not as powerful as full-blown AMG models, the 2009 Mercedes-Benz S550 still packs a mighty naturally aspirated 5.5-liter V-8 that produces 382 horsepower and 391 pound-feet of torque. With an original MSRP of $91,225, the S550 is also one of the most depreciated luxury cars of all time.
Albeit not as luxurious as the S-Class — it lacks standard air suspension and ventilated seats — the W212-generation Mercedes-Benz E-Class still provides a well-equipped, opulent interior and handsome design language. The 2014 Mercedes-Benz E350, in particular, not only delivers 302 horsepower from its 3.5-liter V-6, but it’s also reliable.
A new Mercedes-Benz E350 originally carried a sticker price of $55,327, but used examples now trade for around 20% of that figure. Its modern appearance, comprehensive safety features, and plentiful creature comforts make the 2014 E350 a genuine luxury bargain.
Nowadays, Hyundai and Genesis are two completely separate entities. But back in the day, Hyundai placed its more premium vehicles in the Genesis range. Now known as the Genesis G80, the 2016 Hyundai Genesis sedan can be found with one of two engines: a 311-horsepower 3.8-liter V-6, and a 420-horsepower 5.0-liter V-8. Of the two, the V-8 model is considerably more reliable and comes loaded with luxury features.
The interior of the 2016 Hyundai Genesis is something extraordinary. With high-quality materials throughout, power-adjustable leather front seats that are heated and ventilated, and memory and lumbar support, the Genesis looks like a six-figure car. In reality, a used V-8-powered Genesis sells on average for less than $20,000.
With two Lexus models already on this list, here comes a third — further proof that Lexus cars are nearly bulletproof. The Lexus GS is the brand’s mid-size luxury sedan, slotting between the compact IS sports sedan and the full-size LS flagship. The 2017 Lexus GS 350 sports a 3.5-liter V-6 engine that puts out 311 horsepower and 280 pound-feet of torque.
With an interior you’d expect from a late-2010s Lexus, the GS 350 features a 12.3-inch screen with an integrated navigation system and smartphone compatibility. The cabin is wrapped in leather throughout, though it lacks the more opulent wood trimmings found in pricier models like the LS.
The 2024 Audi A3 is one of the best bargains in the luxury sedan segment. It comes with a turbocharged inline-four funneling 201 horsepower to the front wheels via a seven-speed automatic transmission. Four-wheel drive is optional. The Audi A3 features a mature, no-nonsense exterior that includes a wide trapezoidal grille and curvy body panels.
Though the interior features plenty of hard plastics, it is expertly assembled. You get a 10.3-inch digital instrument display, which can be upgraded to a 12.3-inch screen. If it makes financial sense for you, the pricier Premium Plus variant adds a host of desirable features, including a wireless charging pad and adaptive cruise control.
As per Consumer Reports, BMW outperforms all other German luxury automakers when it comes to reliability. Generally speaking, BMWs from the 2000s and early 2010s tended to carry punishingly high repair costs, but more recent models tell a different story.
The 2020 BMW 440i is one of the best used BMW models money can buy, thanks to its 3.0-liter turbocharged inline-six, more commonly known as the B58. Although you could buy a 440i coupe for a few thousand less, if you want a reliable BMW that costs less than the average new car, the 2020 440i Gran Coupe xDrive is the one to have.
Sharing the same engine as the luxurious, V-8-powered Lexus GS 460, Lexus’ flagship luxury car, the Lexus LS also packs a mighty punch. The 4.6-liter V-8 engine beneath the LS 460’s hood operates with minimal noise while still generating a formidable 386 horsepower and 367 pound-feet of torque.
The 2017 Lexus LS 460’s interior looks like it belongs in a six-figure-plus luxury car, with leather and wood trim throughout the cockpit. Driver and passenger seats are power-adjustable with memory function, and all LS 460 models feature a power moonroof and navigation system, among other amenities.
Just like the aforementioned Hyundai Genesis, the modern, smaller Genesis G70 offers phenomenal value. Albeit much more expensive than the earlier entries, a used 2022 Genesis G70 fitted with the twin-turbocharged 3.3-liter V-6 costs below $40,000 on average and comes with considerably more substance.
With adaptive dampers, the G70 can shift between a stiff, sporty ride and a more relaxed, comfortable one, while 365 horsepower ensures there’s always adequate performance on tap. As standard, the Genesis G70 3.3T also features a comprehensive suite of safety technology, including adaptive cruise control with stop-and-go function, automated emergency braking, automatic high-beams, blind-spot monitoring, and lane-keep assist.
