Hi All. Please excuse my ignorance, but what is the difference between a Vectra-C and a Signum? Here in Australia the Vauxhall Vectra C is badged a Holden Vectra VC. It comes as a CD, CDX or CDXi - no Signum. Mine is the CDXi, topof-the-range. It's a 2003 model: 5-speed auto with tiptronic, 3.2 V6, full leather, the works. (Hence my log-in name - SeeDeeXeye.) The Opel-badged version of my car is the Opel Vectra-C GTS. In Australia, there were only two power plants on offer - the 2.2 4 cyl (in the CD) or the 3.2 V6 (in the CDX and CDXi). No turbo option. I see that in the UK you guys have, what, four or five engine options? And what is the "Estate"? Cheers.
