If you're concerned about the paint, or easier maintenance on keeping the car clean. You might consider paint protection film (PPF), on either the nose, or the whole car. Along with that a ceramic coating.
You're talking thousands of dollars though.
The front bumper of the Tesla is a bug killer, so unless you stay on top of keeping it clean - bug guts are no good for your paint. Also, because of how the body is flared, the rear doors are notorious for getting beat up by rocks etc. So much so, that Tesla has small pieces of PPF to help combat this.
You'll probably want mudflaps (either Tesla's, or aftermarket like Rallyarmor) - to help knock some of that down.
The huge glass roof is nice, and cool to look out of - but after several sunny drives, it get's to be more annoying than anything (in my opinion). Light in your eyes, and a hot head is all it took me to convince me to get a sunshade. You might think about one of those too.
I was going to buy a CCS1 to NACS adapter for the 'just in case' I need to fast charge and there are no superchargers around - but I have yet to have that need, and with a lot of manufacturers announcing to go to NACS, CCS1 is probably not going to make it. So save your money - or if you really want one, wait for the prices to drop.
In the trunk, there are a couple of deep cubbys. On AliExpress I picked up rubber inserts for those cubbies, with carpet fabric lids. It's a nice touch.
