When you fully upgrade a car, all customizations are free. What I didn't know is that they still increase your garage value when you get them! Check it out yourself. Look at your garage value, then go click on some free customizations. Remember, you have to click on the customization, then click FREE to get it. Go back to your garage value to see the increase.
