Everyone has different tastes. I personally chose to do a whole-car PPF the day after I took delivery. Yes, it cost about $5K to do the entire car, but PPF offers a level of protection unlike any other product on the market. It has self healing properties. So if someone scratches your car, or if you get some swirls at the car wash, the heat of the sun makes the scratches and swirls magically disappear. I plan on keeping my car for 8 to 10 years, so to me the PPF is worth the cost. And Xpel PPF comes with a 10-year warranty.
Vinyl wraps are different. They are used more for cosmetic changes, such as having a unique color or finish. They are not quite as expensive as PPF, but they also are thinner and do not have self-healing properties. They will not last nearly as long as PPF.
If you want a unique look and still have the protection of PPF, you can get a satin PPF such as Xpel Stealth. That doesn't change the base color, but it does the car a very unique satin look. I am more of a gloss and shine guy, so that is why I went with the normal PPF.
