I'll be on the opposing side here - I've done PPF on 3 vehicles (wife's Lexus LX570, then when she upgraded to Toyota Land Cruiser, and now my Model 3).
I regret every single one of them and just ordered my MYLR on 9/1, will not be doing PPF on that.
a) VALUE = Unless it is an exotic car, PPF will improve the resale value for your vehicle, but not for the price you paid for it (i.e. spending $3k on PPF won't add $3k in your resale value). Tesla's are unique with the front bumper that seems to be a magnet for bugs/rock chips, but buyers & car dealerships who are looking at your car in 3-5 years will expect wear & tear because they expect rock chips & dents for any 3-5 year old car. I paid anywhere from $1400 to $3500 for my 3 vehicles and do not see that as a smart financial decision
b) AESTHETICS = PPF absolutely will keep your vehicle pristine, and I do not advocate DIY PPF (seen way too many jobs go wrong and you waste hours/sweat/money), but unless this vehicle is literally your baby, not worth it. Unless there is a strong emotional attachment to the vehicle that you plan to keep for a long time, your car will look nice but $3k can get you an extra pair of rims, or pay 6 months of car payment, or pay for Acceleration Boost...all of which WILL improve financial value of the vehicle and enjoyment of the vehicle.
c) DURABILITY = my PPF shop in Dallas does lifetime warranty but so many PPF shops do a pretty bad job, so if it yellows/peels in a few years, you're sort of out of luck. If you are purchasing PPF, do your research on the shop, warranty paperwork and brand (i.e. Xpel) that they use.
