So that's exactly what I've been daily driving for the past eight years. An '02 LX470. It has about 140K miles on it. Just gave it to my daughter.
Other than normal wear stuff like brakes, the only issues I've had with it, are CV boots cracking, AC compressor pooping the bed, a lot of annoying electro gizmo gremlins, and, I think that's about it.
I'd ask about whether the timing belt has been done yet or not. I had mine done at about 110K, just on GP.
All in all, it's been a really good car.
