Hey all - thanks to all of you who helped on my purchase. After a few months of looking I finally picked up a 2020 Eiger Grey P525 with 22" 5 split spoke wheels. Will take delivery later this week. I've owned an LR3 and we will be giving our 2016 LR4 to our son for his 16th birthday, but this is our first RR. Excited to learn all about it.

I am an active member on Rennlist and wrote many of the 997 maintenance guides, and also wrote the buyers guide. I hope to try to do the same for the L405 as I learn all the tricks (and find some time). I started putting together my notes below.
If anyone has any recommendations/additions, please chime in and I will add to the list.

- Front left wheel well, remove the forward fender liner and remove the ground point, if it didn't crumble into 2 pieces (nut+stud, grounds), clean it and squeeze a load of dielectric grease. If it did crumble, grind flat the leftover frame mounted stud, drill and tap a hole into it, and install an aluminum bolt with a load of dielectric grease sandwiched between everything. I think I used an M6 or M7 BMW aluminum bolt, only drilled/tapped in maybe 8-9mm. I tinned the ends of the ground point connections. Steel bolts, galvanized or not will corrode due to dissimilar metals.
- Remove the left side undertray found in the middle of the car. Inspect the active cornering valve block pipes for corrosion, if found clean with wire brush, apply rust remove gel, clean, and paint with POR-15. Do that for any rust found on any and all ACE lines throughout the car. Spray any non rusted lines with fluid film.
- Get some more fluid film or whatever has a long hose attachment and spray the absolute living **** out of the TOP/inside of the fuel tank shield, the massive metal thing in the middleish underside of the car. Undercoat the bottom with POR-15. These will go from thick, "surface" rusted metal to swiss cheese in an instant, super deceiving
