Should I check the MOT history before buying a 2020 Mazda Cx 30 Sport Lux MHEV 4x4?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

How are tyres and brakes typically on a 2020 Mazda Cx 30 Sport Lux MHEV 4x4?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.
