Get your dealer to buy your 17's as part of the deal. My dealer gave me £500 for mine and a discount on the R105's leaving a balance of £775. You'll not get more than £500 selling them privately.
The bumper sets are not fetching very much for some reason ( if i had a cooper i'd be after a set ) They have cropped up on e-bay a few times ( one on at moment IIRC ) and they struggle to fetch any higher than £160-200.
Nice colour choice / combo by the way

as long as you don't live close to me
