How long will a 2002 Lexus LS430 last (150K miles, 200K, or more)?

I am considering a used 2002 Lexus LS430. It is in excellent condition with 79K miles. This is my first time buying used, and I've just had my 1999 American Ford Windstar die out at 150K miles.

I'm debating between this and a new, similarly priced Toyota, but if the Lexus can last a good ten years with roughly 12K each year, then it's the obvious choice for me. I've never had any experience with Lexus (or any import car for that matter), so I'm not quite sure what to expect. For you Lexus owners, how far can I expect this car go without breaking down on me? Thanks a lot for your input!
