I have a 2005 New Zafira. The service is due in Aug 2006. Alperton Vauxhall dealer quoted me £150 for the first interim service. I had a range of quotes from other dealers ranging from £150 - £250 pounds. Does anyone know if the service can be done by other independent garages like nationwide car centres. Or, has anyone had there car serviced at Alperton Vauxhall dealer in Wembley, and did they go a good job. Michael.
