Foot beat me to it plus the one you're looking at has only been in the current owners hands a few weeks I know this cos I know It's previous ownercolour, age, condition and spec all play a part in the price.
The "true" limited editions (champagne, chocolate and silver combos) will maybe be more saught after and hold the price better than stock solid colours.
Splash Creeds are current stock colours and are still produced and are not limited editions.
