It anyone is interested in buying a new or nearly new car, it might be worth having a look on here:
(example of a GSI)
£15968 - not bad for a brand new GSI!!
This site was featured on Channel 5's Fifth Gear a few months ago (they were talking about new Rover MGs I think), so I think its all legit.

Its some sort of auction site but I think you put in the price you are prepared to pay - suppliers compete to offer you the best price - the website tell suppliers what you are willing to pay, and suppliers bid against each other to win your order.

Anyway, thought it may be of interest of someone!!
