Thanx for all that. It really does help to see drivers views rather than try work out what I think the differences would be (and listen to biased salesmen).
Its interesting what you say about the squeaks and rattles on the 450, what were they and how easy was it for lexus to sort?
I do notice that you are talking about the SE-L though and I am still thinking maybe the SE-I would be a better choice, as really the only big thing that I can see that would affect me would be the ML. Seeing as I hardly watch DVD's in my IS, I am not sure that the price difference between the models would be worth paying out for the SE-L.
On the DVD note, how good is the screen to watch DVD's? On my IS if I recline the seat it is virtualy impossible to watch at an angle, is it the same on the rx450?
Does anyone know if it is possible for lexus to fit the ICE/REAR DVD on an used 450? I know you can buy after market alternatives but just wondering if Lexus can fit theirs easily.
To be honest it does look like I am going to get the 450 but, with a budget of around 25k + trade in, I will have to wait another year at least. I will have to just stick to the oil burning IS for now..... Just hate the gear box and MPG (even though it is the same as RX450!)
