Cooper S advice on valuation

[paul81]

Were putting the mrs's 2005 cooper s up for sale this weekend as shes wanting to switch to a coupe. Px is not an option as the dealers are offering ridiculous prices against these cars. Spec is as followed, 05, hyper blue, white bonnet stripes, roof and mirrors, 49k, FSH, leather, panoramic sunroof, 17" alloys, chilli pack, really is in lovely condition although front wheels could do with a refurb. Ive looked on the internet but there is just such a wide spectrum of prices its pretty hard to gain a valuation. We thought around 7.1K, nay ideas??
