Buying one or MOT due? Check these

Coil springs 1.7× typical
Look behind each wheel for a snapped coil (often the bottom one) and listen for clunks over bumps.
Exhaust system 2.1× typical
Listen for a blowing exhaust at start-up and look for heavy corrosion underneath.
Shock absorbers 1.9× typical
Push down hard on each corner: it should rebound once and settle. Look for oily dampers.
Engine warning light 1.4× typical
The engine warning light should come on with the ignition and go out once the engine starts. If it stays on, get the fault codes read before you buy.
Headlight aim
Park facing a wall at night: both dipped beams should sit level and dip to the left.
Tyre damage & cracking
Look for cuts, bulges and cracking on both sidewalls of every tyre.
