European cars are hallowed for their ethereal beauty, rich racing heritage, ingenious engineering, meticulous craftsmanship, and the mesmerizing driving experience they provide. But these exquisitely crafted automobiles – especially high-performance European sports cars – aren’t well-reputed for their reliability. Prominent European luxury automakers including Mercedes-Benz, BMW, Porsche, and Audi have all given birth to countless fast and ferocious machines. Not all of them were durable or reliable, and many even turned out to be disappointments for owners who spent a fortune on them.

However, once in a while, these brands have come up with some rock-solid automobiles with unwavering reliability. The following are ten everlasting European sports cars that could be an enthusiast’s lifetime companion.

10 2014-15 Audi TT

Engine And Performance

The Audi TT is generally considered a reliable compact sports car. Even so, over three generations of the TT, there have been some rotten apples and exemplary performers. The last model years of the second-generation Audi TT swank the best track record for reliability. The 2014-15 Audi TT was never recalled, and for a German sports car, they have relatively low maintenance costs. Sadly, the production of the Audi TT has come to an end, and if you desire a used example, these are the models to seek.

Reliability Data

• Avg. Yearly Maintenance Costs: $995
• Est. Maintenance Costs During First 10 Years: $9,644
• Recalls: 0
• Best Audi TT Year To Buy Used: Both 2014 And 2015

9 2009–2016 BMW Z4 (E89)

Engine And Performance

The BMW Z Series of open-top roadsters have been around for almost 35 years now. Out of its three generations, the middle child, i.e. the E89 generation BMW Z4, has the best stature for reliability. Among these 2009–16 Z4s, the last two model years are the absolute best from a reliability perspective. However, the 2009–11 BMW Z4 models powered by the buttery smooth, extremely reliable, N52 inline-6 motor are also built well enough to last a lifetime.

Reliability Data

• Avg. Yearly Maintenance Costs: $746
• Est. Maintenance Costs During First 10 Years: $13,999
• Recalls: 4 (2009-10), 5 (2011), 3 (2012-14), 0 (2015-16)
• Best Year To Buy Used: 2015, 2016

8 2012-15 Mercedes-Benz C63 AMG Coupe

Engine And Performance

The 2024 Mercedes-AMG C63 S is powered by a cutting-edge 671-hp 2.0-liter plug-in hybrid inline-4 powertrain that is clever but also drab and grating. Ergo, longing for a previous-gen Mercedes-Benz C63 AMG Coupe is par for the course for an enthusiast. The 2012-15 W204 generation facelifted model years are the most reliable C63 AMG models you could get. Among them, the 2015 Mercedes-Benz C63 AMG – the final iteration of its generation – can be crowned as the steadfast stalwart of reliability.

Reliability Data

• Avg. Yearly Maintenance Costs: $1,103
• Est. Maintenance Costs During First 10 Years: $10,734
• Recalls: 4 (2012), 5 (2013), 4 (2014) 0 (2015)
• Best Year To Buy Used: 2015

7 2009-12 Porsche Boxster / Cayman

Engine And Performance

If you hanker a more engaging sports car, the extremely analog, supremely driver-focused Porsche Boxster might be a great option to consider. Out of the four generations, the facelifted second-generation 987.2 Porsche Boxster and Cayman models are the super reliable ones. Other than two recalls that affected very few units, these models have a clean slate regarding inherent issues and boast proven long-term reliability credentials.

Reliability Data

• Avg. Yearly Maintenance Costs: $855
• Est. Maintenance Costs During First 10 Years: $10,734
• Recalls: 0 (2009-10), 1 (2011), 1 (2012)
• Best Year To Buy Used: All models

6 2016–2021 BMW M2 (F87)

Engine And Performance

The most modern car on this list is the first generation F87 BMW M2 that debuted for the 2016 model year and was produced until 2021. The 2016–18 models came powered by the BMW N55 turbocharged engine which was upgraded to the more potent twin-turbo S55 motor in the 2019-21 facelifted BMW M2 Competition. Both these engines have a proven record of excellent reliability, but the S55-powered latter models are found to be a bit stancher.

Reliability Data

• Avg. Yearly Maintenance Costs: Unavailable
• Est. Maintenance Costs During First 10 Years: $13,780
• Recalls: 0 (2017), 1 (2016, 2018, 2019), 3 (2020), 2 (2021)
• Best Year To Buy Used: 2019-21

5 2006 Mercedes-Benz SLK55 AMG

Engine And Performance

Mercedes-Benz pulled the plug on the SLC-Class (previously SLK-Class) in 2020 thus ending the 25-year-old legacy of the sporty, lightweight roadster. Across three generations of the SLK-Class, the 2006 model year is the least prone to reliability concerns. A minuscule number of cars were recalled because of incorrect software calibration, but other than that, the 2006 model is trouble-free. With an intoxicating AMG V8, phenomenal driving dynamics, and unswerving reliability, the 2006 Mercedes-Benz SLK 55 AMG promises eternal delight.

4 2011 Porsche 911 Carrera

Engine And Performance

The storied Porsche 911 has an illustrious history spanning over eight generations and more than half a century. Porsche has created a handful of super-reliable 911s over the decades and choosing one or two model years from that diverse array of cars is a strenuous task. But we've cherry-picked a couple, and our first reliability pick is the 2011 Porsche 911 Carrera. This sublime, modern, and zesty 911 has no complaints registered against it on the NHTSA website whilst a paltry number of cars were recalled once for a minor issue.

Reliability Data

• Avg. Yearly Maintenance Costs: $1,078
• Est. Maintenance Costs During First 10 Years: $18,231 (Average of all 911 models)
• Recalls: 1

3 1986–1991 BMW M3 (E30)

Engine And Performance

Each generation of the BMW M3 is associated with its own reliability concerns and weak spots. However, the first generation E30 BMW M3 doesn’t have any powertrain-related or mechanical issues linked to it, thanks to its over-engineered racing mill. The first-gen M3 is basically a homologation special fitted with a high-revving four-cylinder engine featuring overbuilt components intended for track usage. Hence, the powertrain side is extremely resilient and the only things to worry about are the interior bits that plausibly degrade over time.

Reliability Data

• Avg. Yearly Maintenance Costs: Unavailable
• Est. Maintenance Costs During First 10 Years: Unavailable
• Recalls: 1
• Best Year To Buy Used: 1989-1991

2 2013-14 Mercedes-Benz SLS AMG GT

Engine And Performance

The Mercedes-Benz SLS AMG is one of the brand’s most punctiliously crafted cars, and its last two model years were given the GT agnomen along with a power bump. These 2013-14 Mercedes-Benz SLS AMG GT cars, especially the latter 2014 model, are some of the most reliable supercars money can get you. Other than a couple of recalls regarding faulty airbags and two complaints regarding these recalls, the car bears a pristine reliability record.

Reliability Data

• Avg. Yearly Maintenance Costs: $1227
• Est. Maintenance Costs During First 10 Years: Unavailable
• Recalls: 2 (2013), 1 (2014)
• Best Year To Buy Used: 2014

1 2016 Porsche 911 R

Engine And Performance

The second 911 on the list is a rather special iteration that was born to be a collector’s car, with only 991 examples built among which 300 were allotted to the U.S. market. The Porsche 911 R is powered by a re-purposed, high-revving 4.0-liter naturally aspirated flat-6 borrowed from the 991 GT3 RS, paired exclusively with a 6-speed manual transmission.

With its purist powertrain combo and bare-bones feature set, the 2016 Porsche 911 R is a simple yet super-powered 911 that is built to pass on from generation to generation perennially. The car has to its name a single recall due to improper instructions in the owner’s manual regarding the Child Restraint System.

Reliability Data

• Avg. Yearly Maintenance Costs: $1193
• Est. Maintenance Costs During First 10 Years: $18,231 (Average of all 911 models)
