Always easy enough to have a walk around your car checking a few things, bulbs, tyres windscreen wiper blades and washers. I keep an eye on brake pads and discs when washing the car. Always have a quick look underneath at exhaust and body condition and take a look at all the suspension bushes before going in for a test, easy enough for me with a lift in the garage. Both my Z3 and Z4 have passed with no advisories since I have had them.
