Dallas is right. For the right buyer, like one who would mod it himself, then pre-installed mods do raise the value. But the majority of people would never dream of modding their car and thus look upon them as major red flag, a sign that the car may have been abused.

So, if you can afford to wait for just the right buyer, then selling the car with mods can make sense. But if you need to move it any time soon, you are almost always better off restoring to stock and selling the mods off seperately. Sad but true, this applies to all cars, not just VXs.
