My RMC P100D is scheduled for delivery in Montreal (Canada) next week. I've been reading this forum quite a bit these past few weeks and I still have a few questions for current owners (of any Model S). Feel free to answer one of many questions. =) 1- 3M (new) pro-series film and Opti-Coat Pro+. The (apparently reputable) local installer says he puts a layer of Opti-Coat UNDER the film, then another one ABOVE the film. Anyone has experience with this setup? Does it even make sense...? 2- Suggestion for washing the car after Opti-Coat Pro+? 3- Opti-Glass Pro? Worth it? Would you apply it on the full glass roof as well? 4- Rial Lugano as winter wheels? I've read a catastrophic review on this forum about the Luganos being fragile/prone to damage from potholes... someone broke his 4 rims within weeks. And Montreal is notorious for its numerous and large potholes... I've also read about problems when going reverse with the Rials. Should I stick to the base Slipstreams? 5- Opinion needed here about summer wheels: Silver or gray Turbines on a Red multicoat P100D? Pre-refresh RMC worked well with the gray wheels as it matched the trim under side doors and rear bumper, as well as the fake "front grille". Newer MS trim is painted all red. I'm leaning towards silver Turbines. 6- Bridgestone LM-60 winter tires. They're not suggested for Tesla (load factor) but they're the right size 245/45/19. Some people have used them. Would you still use them on the Tesla? 7- Tires at Costco? Do you trust them with your tires (and save $ since they swap them for free)? Or you always (over)pay the service center to do it? 8- Launch mode: Obviously, won't use it until summer. Does the restriction apply to P100D or only P90D? 9- XM: no XM for me as I went with the full glass roof. I'll miss it... a bit. Just being curious here: does it even exist as aftermarket equipment? 10- Winter mats: Maxpider Kagu vs Maxpider classic vs Tesla winter mats? Interior is all black. Thank you all.
