Easy on the guy, it is not like 2500 - 1000 = 1500 into the pocket, if you have ever had a business (my wife did) you will know what it is like to maintain a place of business, utilities, stock (very expensive), rent, payroll, permits, taxes, insurance and in this case, after sale customer support (e.g. replace broken display).
It all piles up real soon. I don't know the guy but it is not pure honey like you think. Power to him if he makes 500 to 700 in profits. Oh, did I mention labor, that thing called "time" spent putting the thing together and then installing in the car.
All our carpc projects cost a hell of a lot more, we just ignore the fact that we spend the "time", which is money.
