Don't worry about offending anyone, this is suppose to be a truck site, not a flower site.
I don't think they will add any thing at all, if you trade it in, the blue book gives you something like 100. 00 for the custom bumper. If you sell it your self, you might re-coop a little more, it all depends on who is doing the looking, and of-coarse how good you can talk. I have customized many vehicles and even built a few, I do it because I like to do it. I know you never get back what you invested, fact is you will be doing good if you recover 50% on a race car. And on the truck, you would be doing very well if you got 25% of your investment back, that's just how things go. I myself would never buy a vehicle that has been customized, changed much from it's original state. I like to know what has been done, and how it was done. Most don't keep accurate records showing what brand,part number, size, etc. . I do, and I like to have it for future reference. I think anyone that plans on possibly adding to or customizing their truck should sit down and not only plan it out, up answer a few important questions before any action is taken. 1) how long do you plan on keeping this truck? 2) What is the trucks main role, what will you be doing with it? 3) How much do you want to invest? Those three questions will help. Bottom line is you must plan on not recovering any of which you have invested, do what you do for your enjoyment, and enjoy it while it's there.
