Lexus LS series is great, however, with the price tag of 1 million RMB, there are many European cars to choose from. A benz s class or BMW 7 series, even a Audi A8.
For that kind of money, i rather get a brand new S class.
Yes, its reliable, however, you don't want to drive a 10 years old luxury car, so reliability means less in the luxury car segment.
