Keep it stock, or make it your own?

I think if you're going to keep it for a while you can just do what you want to it, but a lot of people want to buy something that is close to stock so if you're planning on reselling it ever, keep it close to stock or at least stock looking. I like the stock look with modern upgrades to the wheels and tires, engine and perhaps a few other things.
That's called restomod or restified. Restored and modified. Stock looking but built to go.
