EXECUTIVES might be top earners but that doesn't mean they have money to burn. So, why is it that some manufacturers cheekily ask £5,000 for extras such as satellite navigation and alloy wheels on their options list?

For those who want to experience the joy of specs but don't like being taken for a ride, Vauxhall has the perfect answer - the Signum Exclusiv. This stylish new model has the sort of standard features which would make any driver drool, including 18-inch alloy wheels and colour satellite navigation and yet prices start at just £17,995 - that's £650 less than the current entry-level Signum.

Vauxhall hasn't scrimped in other areas either. In addition to the six airbags, innovative FlexSpace seating, cruise control and air-con, which is standard equipment on all Signums, the Exclusiv also features front fog lights, silver roof rails and unique interior trim. If that's not enough, then there are still a few items on the Exclusiv's options list. But, rather than taking the opportunity to fleece buyers, Vauxhall's extras are pleasingly good value: upgrading to super-stylish, 19-inch alloys costs a mere £200 for example.

Company car drivers will find that it's not just the Exclusiv's low list price which will make the taxman sulk. Engine options include the new, highly acclaimed 1.9CDTi common rail turbo diesel engines which comply with EuroIV emission laws, so avoiding the 3% Benefit-in-Kind tax penalty.
