A Goblin's selling price depends upon the market and what someone is willing to pay for any particular Goblin. Obviously building one is not a money making venture if/when it comes time to to actually sell it. I would hope that most everyone realizes this at some point, makes the discussion below make more sense.
Not all Goblin builds are the same. Some are bolt togethers of just the supplied kit pieces using just the donor pieces as they were removed from it - the simplicity that is the Goblin as advertised on the website. It's a running and driving Goblin that will provide miles of smiles for the person who enjoys the driving. This build would likely lose the least amount of money when compared to cost to build.
Other Goblins are more meticulously built using cleaned, rebuilt/refurbished, and sometimes brand new parts (from minor to major, stock parts) that offer a premium build with typically better reliability and performance. More love and money was put into this category of build and it most times shows in the finished product. This Goblin should command a somewhat higher price than a basic build due more time and expense to replicate this build if starting from a new kit. But the extra time and expense is also harder to justify in the higher asking price.
Still other Goblins are mildly to extensively modified from the basic parts, kit and donor, to enhance driveabilty and performance, fit and finish, and/or comfort. Those who need more HP, faster corners, quicker stops and showing up that other car/driver just because have added the next level of engineering, design and fabrication to get the most out of their build and driving experience. The DF tube subframe is one example that provides a superior modification for the Goblin that will command a higher price if it were to be sold. These enhancements add value, but like most things they generally do not recover the cost if/when sold. Granted for the in-the-know crowd they can somewhat justify a premium Goblin price, but these are rarely sold - too much soul is put into these to part with them for those who put the blood, sweat and tears into them.
Guess that
@mike_sno posting above got me thinking about how building a Goblin is more a labor of love, the sense of accomplishment, and the reward of the driving experience when it is drivable (I was going to say complete, but is a Goblin really ever complete?). A kit car is more than just about the money spent, as the reality of selling a Goblin demonstrates, as a way to satisfy something inside each of us to scratch the itch. The Goblin market will vary with the seasons and the economy so don't sweat the $$$, it's not worth worry about it.
