Before you view it

What to check before viewing

The Mazda MX-5's most common MOT issues, turned into things to ask about or look for.

Brake discs

High priority

Ask for the date and mileage of the last disc replacement; visually check for a deep wear lip and rust pitting on each disc.

Brake pads

High priority

Ask when the pads were last replaced and check the warning-light history.

Tyres

Worth checking

Check tread depth across the full width on all four; uneven wear suggests alignment or suspension issues.

Suspension bushes and joints

Worth checking

Listen for knocks over speed bumps and ask about recent control-arm or anti-roll-bar work.

Vehicle-specific check

Worth checking

Check the car’s number plate on MOT Wise to see its own MOT history and any recalls for its build years.

Side-by-side

Mazda MX-5 generations compared

Each generation is shown at 7 years old if it has at least 100 MOT tests at that age. If not, or if its cars are too new to be 7, it's shown at another age. We try ages close to 7 first. Newer generations have fewer years of data.

Each row is one generation of the MX-5, shown at the age printed under its fail rate. So rows can be different ages. Fail rate is the share of MOT tests that ended in a fail, retests included. A rating is given only when there are enough tests to place the fail rate in one rating band with 95% confidence.

= the share of MOT tests that ended in a fail. Retests count as tests.
Fail, no pass in 3 days
= the share of MOT tests that failed and still hadn't passed 3 days later. A fail that passed a retest within 3 days, even the same day, isn't counted.
Dangerous
= the share of MOT tests where the tester marked a fault as dangerous. It is against the law to drive the car until it is fixed.
Still registered at 10 years
= the share of cars still registered (taxed or declared off the road) 10 years after they were first registered.
