FAQs

Is a 2017 Tesla Model S reliable?

2017-registered examples passed 83.4% of their MOT tests (7,455 tests, 2023–2025), -0.6 points versus all UK cars registered in the same year. At roughly 9 years old with a median 70,917 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 Model S?

The median tested example shows 70,917 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
