I have known so many people who had problems with Corrola's starters. They had to replace the starters at ~80k mi.
I have seen so many times that quite new (2002 and after) Camry's on the road had burned-out rear lights. The owners might not even know their rear lights are burned out.
My point is Toyata uses cheap parts, like the O2 sensors, bulbs, etc. I think my Accord had much better quality than Camry, it never gavee me any trouble after the original warranty expired.
You can not tell the difference between a toyota and lexus without driving one. Lexus gives you much more luxurious feeling, and its build quality is also higher: it uses seamless molding, while Toyata still uses normal molding.
