I've got a 2003 Vectra CDXi auto. The 2006 has had the gearbox issue update which plagued the earlier model so no issue there. As for parts, dont buy them here As an example, for a water pump for those, Holden wanted $550! From the UK, $55AUD, enough said. Pretty comfy car, plenty of extras etc. In saying that, the Mazda 6 has a good rep, although I haven't driven one.
