Most people don't want to buy someone else's mods so for this reason it will be harder to sell but if the mods have been done well and by people who know what they are doing then it should be worth more than a standard setup to the right person.
You have essentially a finished car to your personal tastes - not many peoples taste.
I don't know enough to comment fully on what you have done or if you know your stuff to trust what you have done. This will be the
problem, only people who are very knowledgeable will be able to judge what it is worth (after a very detailed inspection). Even after that they will no doubt think they know better. For example, I know lots of people who really don't like the Koni FSD / Eibach setup.
Some may be sucked in by the extreme power and be happy to pay good money for it.
Most will just steer clear due to the level of mods you have done.
Good luck selling it.
You could sell the mods off and put car back to near standard? Maybe get more money that way.
Saying that, i would not want a car that was previously modded to a high spec and then put back to standard. I would prefer one that has been factory from the start.
