If I ever traded up my mk4 (and that's a big 'if'), for another Lexus, it would be for a 430. I really like the look of the cabin on those, but I am also aware of the niggles that crop up on that model. So, for now, I'll stick with my trusty old LS400. It's still a delight to drive every day even if it is 15 years old and is just as reliable as some 5 year old cars, I'll wager.
