I hear you buddy and its a difficult one! The wheels are actually in lovely condition, the gold is obviously not to everyones tastes, so if someone wants to spend £200 (which i have dropped the price by) its kind of their choice. I appreciate the tyre comments but again, both front tyres have plenty of tread, so its personally preference to change them. So thats £400 or so, you dont "have to spend".
And as you said in your wheel refurb thread, you paid £3k for your wheels alone, well if you spend the £200 on these for your colour choice, they would effectively look brand new wheels for less than half the price and still be worth similar money in a year or more
People pay £800 or so for Rotas with poor brand tyres 2nd hand that will be worth about 50p in a couple of years that is if they havent broken/cracked (and yes that has happened to me before anyone asks)
Make an offer without the front tyres is the only way i can try to assist.
