Decided to have the Cambelt changed as the last one was done in 2004 at 27,300 miles. Had the waterpump and thermostat, alternator belt and antifreeze changed - wierd orange colour as its now long life they use - and I have gallons of blue 2 year stuff! Everything changes! Cost - a whopping £300 plus VAT at 20% but that did include genuine Mazda parts troughout.
