Paint chipping has been an issue for some time now. IS300 boards are full of paint chipping issues. Some people have gone so far as to make the dealer touch up the chips, and install some form of paint guard at cost. Some say that the paint formula for some colors was changed a few years ago due to some sort of regulatory thing, so the paint isn't as tough as it used to be. Who knows?
And I'm not ridiculing when I suggest someone would buy your car. If it's that big of a problem for you, that should be a relief. However, solutions to your problems have been offered here and more or less rejected for financial or other reasons. You'll either have to take action at some point or not. That's your choice. However, I do find it somewhat unusual that you can afford a luxo lexus, and a fairly new van, yet cannot afford to protect your investment because Christmas is coming. But, that's your own personal problem, not ours.
There is a section here in each car forum to list problems and issues, if that is your intent.
This is not intended to be harsh, but just the logical thinking that comes from reading the posts.
