Well mines Albi blue like yours with same silver raiders so nothing different from you to start with although a few minor scuffs, but the anthracite has transformed them totally....the offer was £207 if i dropped the wheels off...but once i was there i thought sod it !!! so they charged tenner extra to take tyres off and put back on after with balancing.
Then i had special wax coating as you do and centre caps done so added up to £300 with vat.....bit of a jump from 207 but im more than happy with end product and doing without hassle of taking wheels off myself and being without car.
Will take a picture soon as i can for you
