Thanks for the info. As of yesterday, I've officially joined the club. The car is a 2010 IS 250 C in Smoky Granite Mica w/Alabaster interior, Navigation, Luxury Package, and chromed 18" wheels. I would actually have preferred 17" wheels for the taller tire sidewall. What can I say; I'm older, and would trade off a little sharpness in handling for a more comfortable ride. It was purchased from a Lexus dealer but not a CPO. 30k miles with just under a year remaining on the 4/50k warranty.
Paint has minor hologramming from an amateurish detail job. I'm a detailing enthusiast so sometime in the next few weeks I'll strip what's on it and hit it with some Menzerna SP4000 and then try one of the new coatings (Gtecnniq, CQuartz, OptiSeal, etc.) rather than sealant. Since I'm new to the coatings, I'm going to try it out on my daily driver first.
