1. Brakes - Transmission
When it comes to ensuring you are buying a safe car, the brakes are one of the most important things to check. Does the hand-brake or parking brake hold the car on a hill? When it comes to the test drive, the mechanic will find a safe straight piece of road to test out the brakes. The brake test will determine that the brakes have a solid feel and the car brakes in a straight line. Also be sure to listen carefully for squealing or grinding noises.
The mechanic will be getting a feel for the transmission during the test drive. The car should shift smoothly. Automatics shouldn’t have any delay in gear selection, and manuals shouldn’t crunch or grind when going into gear.
