No offense but you have the money. You bought the truck. You bought two Lexus vehicles. You used them while you could then you sold them. The truck is new and shiny and exciting. You're not going to drive it? Sure you are. Same as driving it home. I am sure driving it during normal use it will incur as much damage as the couple hundred miles home.
Have the dealer do PPF. It might be more but is it more than your local shop plus the armor you want to buy? I have a sport package and did PPF on the front. The rest comes clean in the car wash.
The reason I have the money is that I don't abuse and throw away my stuff. I make every effort to take care of my things, cars, tools, tractors, guns etc. And not that it's anyone's business, the GS350 was a company car that was gifted to me when I retired after 37 years.
As I stated before my truck is not a garage princess. It is my daily driver and of course it will get it's fair share of dings, dents, scratches etc...That doesn't mean I go looking for two beaters to park between or pull it out of the garage during a hail storm just because I could!
I'm not trying to tell anyone how to take care of their truck, simply relaying what I did. For all I care wash your car with brillo pads.
And you a right about having the dealer install the PPF. I should have done that in hindsight but that cow is out of the barn.
