Should I check the MOT history before buying a 2016 Sinnis Js?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

What tends to go wrong

Across 125 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 30.1%

Rear Tyre worn close to the legal limit · Rear Tyre tread depth is below minimum requirements of 1.0mm · Front Tyre worn close to the legal limit

Lighting 26.5%

Drive chain slightly loose · Headlamp aim too low · Headlamp not working on dipped beam · …

Usually cheap to fix. Worth confirming all lights work before collecting.

Brake wear 21.2%

Front Brake pad(s) close to minimum limit · Front Brake binding but not excessively · Front Brake disc worn, pitted or scored, but not seriously weakened

Ask the seller when brakes were last serviced. If they don't know, factor in the cost.

Suspension & steering 14.2%

Steering headbearing has slight free play · Steering headbearing slightly stiff or notchy · Nearside Front Shock absorber has a light misting of oil

Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
