Its a 56 plated 2006 1.9TDI Elegance Hatch with 45k on the clock, nice nick and full history..... any idea of a trade and retail value for it ?

Do a whatcar valuation on their website. They are never that far off the mark.

I'd imagine retail around the £5k mark...maybe a bit more, and trade in probably about £3500?....private sale about £4500. But it does depend on what values are like in your area.
