Which car can be sold for the most money when fully modified?
Solution 1:
Along with the Sultan & Futo, there is the Dominator, which is very profitable when fully modified.
The Schafter goes for around $120,000-$130,000 when fully modified, but it is rare.
From what I remember, the Gallivanter Baller and the Lampadati Felon get you $9000 when sold. These are the most common profitable cars to sell non-modified.
It may get you more if you customise it, but I don't see the point in spending time, only to get a bit more money.
