What to check before buying a 2020 Zs Excite Vti-

Before buying a 2020 Mg Zs Excite Vti-, focus on the areas it most often fails on. Tyres accounted for 6.0% of tests for this year.

Tyres (6.0% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Brakes (5.2% 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 (2.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.

Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
