According to an analysis of test data by the DVSA, Ferrari owners are statistically more likely to see their exotic engines pass an MOT the first time than drivers of any other make of car.
The Italian supercar maker had an impressive TÜV inventory rate of 93 percent in 2020 for vehicles aged 3 to 15, which suggests that the ultra-expensive supercars can stand the test of time – and their owners, despite their heavily used performance parts As expected, pay special attention to their beloved engines.
The top of the list has been dominated by prestige automakers like Bentley, Aston Martin, and Porsche, while the other end of the spectrum shows that Chevrolets have the highest failure rates of any brand.

Of the 6,362 Ferraris up to 15 years of age that had an MOT in 2020, only 443 failed – giving the manufacturer a statistically higher success rate than any other automaker last year.
Unsurprisingly, the front-runners who passed the test were mostly luxury brands – the cars that cover fewer annual miles and spend most of their time in the garage or in private collections.
Bentley (91.2 percent), Aston Martin (90.3 percent) and Porsche (88 percent) were behind Ferrari with the best average pass rates of all car brands.
Mainstream brands with a high success rate included Infiniti (87.3 percent success rate) – Nissan’s luxury spin-off brand that is no longer sold in the UK.
Tesla was another strong performer, though the brand has been associated with poor production quality in recent years.
Of the 7,853 U.S. electric models tested in 2020, 1,055 failed – a success rate of 86.6 percent.
This was slightly better than Japanese automaker Lexus – a regular leader in vehicle reliability survey rankings.
The manufacturer – owned by Toyota – had a performance of 82.6 percent at TÜV and was ahead of Maserati, Mercedes-Benz and the surprise manufacturer in the list, DS.
However, DS Automobiles has only been an independent brand since 2015, when it was no longer officially recognized as a sub-brand of Citroen, which means that the vehicle pool analyzed for the study is significantly younger than the average for most other brands from 2005.
About 7% of Ferraris under the age of 15 failed their MOT last year – that’s the lowest failure rate of any car brand, according to DVSA figures from BookMyGarage.com

Chevrolet came last, with just over half (54.4 percent) of its cars passing through for the first time – although the U.S. brand hasn’t sold any of its mainstream models in the UK since 2014, and therefore only a sample of older vehicles that have suffered from wear and tear.
Jessica Potts, Marketing Director at BookMyGarage.com, who requested the MOT data from DVSA, said it was “no surprise” that luxury brands like Ferrari do best when they have a MOT as they are likely more valued than they are a mainstream car – and the quality you would expect from such an expensive engine.
“Owners of prestige car brands often drive fewer miles a year as the car is likely not the owner’s only vehicle and they are usually serviced to very high standards,” she said.
“TÜV inventory rates are less an indication of brand reliability than of how well the owners maintain their car and how much the models of a particular brand are becoming a“ workhorse ”.
“That being said, there is a clear dominance of more mainstream Japanese brands in the top 10, perhaps proving the notion that Japanese cars are actually very reliable.”

More than a fifth of the almost new cars fail their very first MOT, DVSA statistics show
An inspection of the cars that passed their MOT for the first time (at the age of three) showed that Ferraris were ahead of the curve there too, again ahead of rivals Bentley and Aston Martin – albeit with Porsche lagging behind in sixth place .
Of the mainstream brands, it was purely Japanese brands that filled the rest of the top 10, with Subaru and Lexus taking fourth and fifth and Honda, Infinity, Mazda and Suzuki taking seventh through tenth, respectively.
At the other end of the range, SsangYong was less successful, finishing last with a failure rate of just 78.1 percent – a pretty hard figure for customers who had only launched their new cars 36 months earlier.
However, success in a test center depends as much on the maintenance of the holder as it does on the longevity of the engines and their parts.
The most common TÜV mistakes are due to neglect of the owner – such as the 6.8 percent of cars that fail the assessment because of badly worn tires.
The average success rate of the cars tested for the first time was 78.1 percent, as the figures show.
