A good start is to make sure that we have access to the tires, preferably located within 25 meters of the car. We also value our employees very much, so if for their safety you can place the car on a flat surface and with the handbrake on, we would be very grateful.
Last but not least, if your wheel bolts have lock nuts it is very important that we have access to it. These come in a large number of different varieties, so unfortunately we don't have the option of having these as part of our standard tool.
