Before you view it

What to check before viewing

The BMW Z3's most common MOT issues, turned into things to ask about or look for.

Brake pipes and hoses

High priority

Look under the car for corrosion or chafing on the rigid brake pipes near the rear axle.

Suspension bushes and joints

Worth checking

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

Tyres

Worth checking

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

Suspension

Worth checking

Inspect the suspension carefully and ask the seller for repair history.

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.

The share still registered can reflect demand, the cost of repairs, exports, write-offs and how owners use the car. It isn't proof of how long the car lasts mechanically.

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.
