Well more than likely this is a actaul scale type model meaning its accurate it says it includels a full interior and under carriage im assuming they are brokering it for someone and it has a polycount of almos 300,000 which means its more than likely movie quality considering all these factors the modeler probaly spent a good deal of 2 months working on this if not more so if you assume that hes charging basicly 2months salary plus the cost to cover the brokering which is probaly 30 to 50 percent so basicly hes probaly asking about 4500 for the model which if its a fully detailed realistic high poly model really isnt bad considering it will be bought by a ad agency or archetexture firm maybe a film agency who has tons of cash sometimes its faster and easier even more cost effective to buy this model for a comercial you need in 2 weeks rather than to try and pay a modeler or team of modelers to do it but i agree looking at it at a glance makes you think Damn ! lol
