What to check before buying a 2020 Grandland X Businss Ed T A

Before buying a 2020 Vauxhall Grandland X Businss Ed T A, focus on the areas it most often fails on. Tyres accounted for 3.2% of tests for this year.

Brakes (2.4% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Lighting & signalling (1.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
