For context, I own ADAC GT Masters Experience 2014, the GTR3 pack, European Tracks pack, and one livery from ADAC GT 2013. So I'm wondering why my price for the ADAC GT 2013 pack is 880 vRP, and 2015 is 227 vRP? 880 seems awfully high for 23 liveries, unless there's something else about 2013 that I'm not understanding.
Are you sure you are looking at the GT Masters 2013 pack and not at the whole Experience? http://game.raceroom.com/store/pack/adac-gt-masters-experience The 2013 pack should be much cheaper for you.
I'm looking at the GT Masters 2013 car pack, 880 vRP: http://game.raceroom.com/store/cars/adac-gt-masters-2013 GT Masters 2015 car pack, 227 vRP: http://game.raceroom.com/store/cars/adac-gt-masters-2015 But now you mention the Experience, for me it's 1449 vRP!
