Check past MOT emissions readings in the car's history: rising readings can mean catalyst or sensor problems.
Windscreen washers 1.6× typical
Test the washers and wipers: a cheap fix, but a very common MOT fail.
Suspension ball joints 2.9× typical
Listen for knocks over speed bumps and feel for wandering or vague steering.
Handbrake performance 1.6× typical
Check the handbrake holds the car firmly on a slope.
Headlight aim
Park facing a wall at night: both dipped beams should sit level and dip to the left.
Brake performance
On the test drive, brake firmly: the car should stop straight with no pulsing through the pedal.
