The aim of this pack was to drive traffic to MasterFit centres where ageing Vauxhall cars could receive all the care and attention they deserved, post warranties expiring. As well as promoting the repairs service, we pointed out that booking a vehicle ‘health-check’ might well prevent things going wrong in future. Rattles are perhaps the most obvious and infuriating sign that something’s broken or failing. So the pack included some loose components that ‘rattled’ to dramatise the point. Check out the accompanying 'Rattle, Part II' for proof it worked.
