What do you look for while buying a miniature ?

So had a conversation between a gentleman here and he commented " Only kids looks for detailing while purchasing a model car "

As a miniature car collector for few years I've always given priority to detailing over anything else. I'm happy to spend 1.5K on a MiniGT than a previous year Hotwheels, 3K on an Inno64 than a STH ( For the same model ).

Everyone has their own taste while collecting and I respect that. Let me know what attracts you to purchasing a model ? Is it the Brand, Model, Maker, Exclusivity, Nostalgia etc etc. What type of a collector are you ?
