Good, but could do better. That'Â’s the message from owners of Vauxhall'Â’s best-selling Vectra. Practicality is rated above average, while running costs are surprisingly low for such a big car. However, there are clearly areas which need attention if the model is to match FordÂ’'s Mondeo, which is 10 places higher. You tell us that handling isn'Â’t sharp or accurate enough, while the controls need to be better weighted; a finishing position of 86th in the ease of driving sector is a disappointment.
