Just which used sport sedans are the best when it comes to maintenance costs-- and specifically, which models can you actually afford to maintain? After all, there are many reasons you choose the sports sedan you choose. Some shoppers prefer the most powerful machine for their dollars. Others prefer the most opulent cabin. Others may prefer to stick to a Cadillac or BMW, having dreamed of ownership since childhood. Some shoppers seek out used models like the Genesis G70 or Audi A4 specifically for the manual transmission. Others may choose their sedan based on a favorite feature, the latest connectivity tech, or a high safety score.Maintenance costs are an important consideration for many sport sedan shoppers, and if you're one of them and in search of a ride that won't vaporize your bank account when it's time for service or repair, read on.Below, we recommend ten affordable used sports sedans that you can actually afford to maintain - based on expert scoring, input from owners' communities, and a look at the parts and systems used to build each model.Before we get started, just keep one important thing in mind: neither a used car's position on an internet ranking list, nor its high reliability score from expert sources, is any guarantee that the specific unit you're considering is healthy, reliable and trouble-free. The only way to do that is to have it inspected thoroughly by a qualified technician before you buy. Still, noting some specific affordable models highly-rated for quality, dependability, and straightforward maintenance should help point you in the right direction.For this feature, we're considering used modern luxury sport sedans widely available for $30,000 or less based on their CarBuzz Marketplace value. The models chosen for this list often include high Quality and Reliability scores from J.D. Power, and are built using proven parts and platforms that should bolster long-term reliability and keep your repair and servicing costs to a minimum. All pricing and performance figures are approximate. 2020 Acura TLX 2020 Acura TLX White Front Angled View Driving 0-60: 6.1-7.5 seconds / J.D. Power Q&R: 81/100 The 2020 Acura TLX has a few valuable assets for the sport sedan shopper after the lowest-possible maintenance costs. First, this model year represents the final year of the TLX's first generation, allowing shoppers to capitalize on the benefits of a recent facelift that added new style and value. Save a few bucks by opting for a four-cylinder, front-wheel drive model, which you'll find to deliver livelier handling and better fuel mileage than the larger V6, which only comes in AWD.With plenty of production experience into this machine, as well as the widespread use of engines and drivetrains proven in other Honda and Acura applications, the 2020 Acura TLX offers plenty of selection on a second-hand sports sedan that's highly-rated for quality and dependability. Today, you'll find plenty of selection under $30,000. 2021 Lexus IS 2021 Lexus IS F-Sport Silver Front Angled View 0-60: 5.5-7.0 seconds / J.D. Power Q&R: 88/100 The Lexus IS is a sure bet as a great-driving sport sedan that's backed by a stellar reputation for reliability and dependability. According to J.D. Power data, the IS achieved top marks of 'Great' or even 'Best' when it comes to Quality and Reliability - and that's been consistent for many years. This suggests that Lexus gets something just right with the IS for every generation, demonstrating consistently high scoring among competitors for a reliable driving experience.Opt for a 2021 or newer unit if it's in your budget to take advantage of the latest third-generation facelift, which boosted the IS's style and added more standard premium content. With multiple engine and driveline choices available and some of the longest-running powertrains in the segment under the hood, you'll find plenty of selection for around $30,000. Save a few bucks by opting for a rear-drive model if you don't need AWD traction. 2022 Genesis G70 2021 Genesis G70 Red Front Angled View 0-60: 4.5-6.0 sec /J.D. Power Q&R: 87/100 The 2022 model year brought the Geneis G70 a freshened new look and interior to help in its battle against other established sport sedan competitors with which it competed. You'll find rear-drive or AWD available, as well as a turbo engine with a choice of 4 or 6 cylinders. At this point, the Genesis brand was making major headlines for its top scores for vehicle dependability, and the specific 2022 Genesis G70 earned an 87/100 score from J.D. Power for Quality and Reliability.Built using engines, components, electronics and assembly plants with tremendous mass-production experience in other models. While the G70 is a relatively new car, it has a lot of well-proven parts under its skin engineered for commuter-car maintenance levels. Set a purchase budget of around $30,000, and you'll find plenty of selection. 2022 Infiniti Q50 2022 Infiniti Q50 Blue Front Angled View 0-60: 4.6-6.1 sec /J.D. Power Q&R: 83/100 It's no major surprise that the Infiniti Q50 finds a place on our list. By the time 2022 rolled around, Infiniti had been building the Q50 in this generation for 9 years. More modern turbo V6 engines give shoppers more efficiency and power choices, with rear or AWD available. With loads of experience into this platform, a well-proven 7-speed automatic and dated-but-reliable infotainment systems, the Q50 seems to have fended off trouble from common maintenance and reliability sore-spots among modern sport sedans. Nissan knows a thing or two about building a long-lasting V6 engine, too. It built the V6 that won engine of the year more times than any other. 2022 Mercedes E-Class 2022 Mercedes-Benz E-Class Silver Front Angled View 0-60: 4.4-6.6 sec /J.D. Power Q&R: 81/100 The fifth-generation Mercedes-Benz E-Class launched in 2017, received a facelift for 2021 before being replaced by an all-new, sixth-generation car for 2024. J.D. Power shows strong Quality and Reliability scoring, with this generation E-Class earning 'GREAT' scores for all model years between 2019 and 2023 inclusive, aside from a slight dip to 'AVERAGE' territory for 2021. Mercedes was making some big strides in interior styling at this point in time, giving the E-Class arguably the most beautiful interior on our list. A 2022 or 2023 E-Class of your liking should be reasonably easy to find for around $30,000. 2022 Polestar 2 504312_20200624_Polestar_2_Performance_Pack_001 0-60: 4.4-7.5 sec /J.D. Power Q&R: 58/100 The Polestar 2 is a tricky machine to recommend on a list of other models so highly-rated by J.D. Power for Quality and Reliability. A relative newcomer, the Polestar 2 has a mediocre 'fair' score in this metric, but as the only EV on our list, it's worth noting that when it comes to 'cheap to maintain', this is probably the best pick on the page. Shop smart: you'll want to find a unit that's been treated to all recalls and software updates, and one familiar to its selling dealer, ideally as part of a Certified Pre-Owned (CPO) program.Remember that early-onset problems have likely been rectified by the previous owner under warranty, and that the Polestar 2's battery has an 8-year, 100,000-mile warranty in effect. With few moving parts, no oil changes and long-lasting electric brakes, long-term maintenance basically becomes tire changes and wiper blades. 2021-2022 BMW 3-Series P90323745_highRes 0-60: 4.4-5.3 sec /J.D. Power Q&R: 81/100 The seventh-generation BMW 3-Series arrived for the 2019 model year, with a facelift applied for 2023. According to J.D. Power, the 2021 and 2022 model year 3-Series have particularly high scores of 'GREAT' for Quality and Reliability. Sportier models run BMW's 3-liter straight-six engine, a technological marvel evolved from decades of experience. It's a similar story for the 8-speed automatic. The four-cylinder turbo on entry models should prove sufficient for most drivers looking to save a few further bucks on gas. 2013-2018 Audi A4 336358 $41,000 / 0-60: 4.4-5.3 sec /J.D. Power Q&R: 87/100 From 2013 to 2018, Audi enjoyed a great run of top Quality and Reliability scores from J.D. Power for their very popular A4 Sedan. The model year selection here covers two generations: with the 4th-gen facelift arriving for 2013 and the fifth-gen car arriving for 2017. Translation? A late fourth-generation A4 or early fifth-generation A4 show consistently good scoring for Qualtiy and Reliability, and come backed by years of mass-production of one of the world's most popular engine and driveline teams, which has found homes in countless other Audi and VW models-- making it easily serviceable just about wherever you live, should the need arise. This is one of the only cars on our list you'll find available with a manual transmission, too. You'll find a large selection for around $20,000. 2018 Cadillac ATS 2.0 2015 Cadillac ATS Coupe Red Front Angled View Driving 0-60: 5.8 sec /J.D. Power Q&R: NA There was just a single generation of Cadillac ATS, which debuted in 2013 after an extensive engineering and development phase that put the BMW 3-Series of the day square in its sights. The resulting car gained tremendous popularity with enthusiast drivers and formed a tuning community around it, many members already familiar with tuning earlier versions of the robust 2-liter turbo four from earlier models.The ATS isn't rated by J.D. Power, but its owner's community seem to generally love the dependability and fun factor of the 2-liter turbo engine, available six-speed manual, and light, lively driving feel. Plenty of maintenance work on the ATS is also DIY-friendly, if you want to save a few more bucks. You'll pay considerably less than $30,000 for one today. To save the most on maintenance, skip the optional V6 engine option. 2016-2017 Volvo S60 308768 $40,000 / 0-60: 5.5-6.5 sec /J.D. Power Q&R: 85 The second-generation Volvo S60 hit the road for 2011 and carried on through 2018 with several updates and a facelift. This was the last S60 before Volvo's new-age styling kicked in, and you'll find a classic combination of turbo straight-six power, excellent AWD performance, stellar winter driving confidence, and some of the best seats in the business. Here's another low-cost option like the Cadillac ATS above, this one coming with high Quality and Reliability scores from J.D. Power in 2016 and 2017, coinciding with the approaching end of the model's life cycle. With earlier bugs ironed out, a healthy 2016 or 2017 S60 should provide an affordable-to-maintain driving experience that's fun, confident and comfortable.
