What to check before buying a 2020 Ceed Gt-Line Lunar Isg
Before buying a 2020 Kia Ceed Gt-Line Lunar Isg, focus on the areas it most often fails on. Tyres accounted for 5.2% of tests for this year.
- Tyres (5.2% 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 (5.0% 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.
- Brakes (1.6% 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.
