What to check before buying a 2020 Vivaro 3100 Dynamic S/S

Before buying a 2020 Vauxhall Vivaro 3100 Dynamic S/S, focus on the areas it most often fails on. Lighting & signalling accounted for 8.7% of tests for this year.

Lighting & signalling (8.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Brakes (6.9% 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.
Visibility (6.9% 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.

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