Essential Pre-Purchase Step

Buying a used Dacia Spring? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Dacia Spring Buyers

Test public DC rapid charging and home AC charging to ensure the onboard charger locks and begins charging immediately
Listen for clunking or knocking from the steering column when turning the wheel at parking speeds
Check the high-voltage cable connector under the bonnet for secure mounting and water seals
Verify tyre wear across the lightweight 14-inch or 15-inch tyres
