An MOT bay is one of the most costly purchases that a garage can make. Important factors for the equipment are a good range of capability and, because of the commitment needed to be given to customers, a high level of reliability. The supplier should have a first rate understanding of VOSA requirements, be able to offer a high quality drawing service that is able to provide clearly defined layouts plus, very importantly, ground work details and electrical specifications. A good level of back-up service, particularly in the long term, is vital.
