What to check before buying a 2020 Discovery R-Dyn Hse A

Before buying a 2020 Land Rover Discovery R-Dyn Hse A, focus on the areas it most often fails on. Tyres accounted for 7.2% of tests for this year.

Tyres (7.2% 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.
Visibility (4.1% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Lighting & signalling (2.4% 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.
