2018 Audi A6
Reliability Score: 82/100
Audi has always sat between BMW and Mercedes, offering a good balance between raucous fun and sleek interior comfort.

You can grab one now for the average price of $19,285.
Reliability And Maintenance
Audi is a brand that doesn’t have the most stellar reputation when it comes to reliability, with quality issues that span generations. However, even among duds there are a few diamonds.

2020 Mercedes-Benz E-Class
Reliability Score: 83/100
The E-Class competes in the same segment as the Audi A6, meaning it features an impressively spacious interior. Where its rivals go for a somewhat more playful approach, the E-Class is about calm confidence. On the inside, it feels like a baby S-Class, with a cabin loaded with high-end materials and cutting-edge technology. Most impressively, though, you can take one home for an average price of $34,876.

Just like Audi, Mercedes-Benz doesn’t have a fantastic track record when it comes to reliability. There are some standouts, though, and the 2020 E-Class seems to be among them.

2022 BMW 5-Series
Reliability Score: 83/100
Rounding out the ‘big three’ German automakers, BMW offers the 5-Series sedan in the midsize segment. The 2022 model year isn’t the latest generation, but that isn’t exactly a bad thing. Over time, the 5-Series has ditched its driver-focused ideology and become more of a luxury cruiser, focusing on delivering a plush experience above all else. Currently, 2022 models list for an average of $37,824.

Modern BMWs are actually among the most reliable new cars that you can buy, despite what certain nay-sayers may try and tell you. The 2022 5-Series is a great example of this, with the choice of either a proven four-cylinder or a smooth inline-six. On average, maintenance costs for BMWs tend to be high, but estimates by RepairPal put them on the lower side of the segment.

2020 Volvo S60
Reliability Score: 84/100
A brand that is often unfairly left out of the conversation is Volvo. While maybe not as flashy as some German rivals, the S60 is one of the most comfortable and well-equipped luxury compact cars out there. Where other models in this segment make compromises to either comfort or performance, the S60 perfectly walks the line between the two. Thanks to their heavy depreciation, you can grab one for a bargain, with $22,482 being the average price of a 2020 model.

2023 Genesis G70
Reliability Score: 84/100
Genesis is a fairly new player in the luxury world, having only become a standalone brand back in 2015. Since then, they have done a lot of work to set themselves apart.

2022 Genesis G80
Reliability Score: 87/100
Genesis makes the list a second time with their fantastic midsize G80. Despite costing thousands of dollars less than its rivals, the G80 delivers an interior that is just as plush, if not more so. Ride quality is infallible and both its turbocharged four-cylinder and twin-turbocharged V-6 engines deliver impressive power. They don’t hold their value particularly well, which is great for used buyers as you can get a 2022 G80 for an average price of $35,796.

Once again, Genesis proves that their cars are particularly sturdy, with a second sedan scoring highly when it comes to reliability. The build quality is superb on the G80 and its two stoic engines have proven themselves in a number of different products across the Hyundai brand lineup.
