I look at it like I look at these forums. If someone was to look at this forum, the 460 is the worst car Lexus ever released
Until you look at the OTHER forums and realize that it's enormously disproportionate at those other forums. The concerns here at CL are ridiculously minor in comparison. Go see the E65 forum at Bimmerfest......when you see threads like "engine burning oil", "transmission replaced", "3 weeks in the shop for engine replacement", "failed emmissons test again", etc. you realize how good we have it.
As for the warranty......that isn't a carte blanche for worry-free driving. Many warranties (especially when covering a vehicle like the V12 AMG), wll not cover everything. seals, gaskets, (including valve-stem), bushings etc are often not covered. When I looked at my warranty for my LS closely, I promptly requested a refund. Too many exclusions. When I used my E65 as an example for any future repairs, almost NONE (including the valve-stem seals), would have been covered.
