What to check before buying a 2021 Trafic Sl28 Black Ed Engy
On a 2021 Trafic Sl28 Black Ed Engy, suspension is what the MOT record says goes wrong most — it appeared in 4.5% of tests. Check these areas before you commit.
- Suspension (4.5% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (3.6% 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.
- Tyres (2.7% 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.
