You have to realise that some people pay someone to do everything for them. AND they get reamed every time they get something done. Thats probably why he wants so much, because he thinks that is what it would cost to replace. A lot of these feature cars in magazines are built by someone who gets payed by the owner who has no idea.
If you really want to see a dreamer, check out ebay at the moment. there is a 1200 ute with an A12 with twin su's on it with a rough paint job in the engine bay and he reckons he's spent something like 30 grand on it!

His buy it now is 20 grand!! I have no idea how you spend 30 grand on what is essentially a stock 1200 ute with a paint job and mags. He must have used 50 dollar bills as sound deadener on the floor of the cab, OR more likely he has paid someone to do everything and they have jumped at the opportunity to make a fortune off him.
