and price difference.
MY hse could easily be passed as a vogue.
it has exacly the same options as the vogue all except for the sat nav. I have compared it to my friends vogue and theres no difference apart from the the sat nav.
but this was because the original buyer paid for all the optional extras, you can find some HSE's with jack sh!t, ie no xenon headlamps, no reversing sensors, self dimming mirrors, heated seats / steering wheel.
but if you find the right HSE with the extras you want they can be up to £1500 cheaper than the vogue.
