Looks almost the exact same deal as me, part x in my is250 in blue for my rx450 in light blue metalic.
im sure your have many happy years of driving from it.
I know when I bought mine I have gone through several phases of loving it to thinking the novelty had worn off.
now some 11months later I still enjoy the car though. There were times I felt it needed a bit more go but then I was comparing it to my gs450. Overall, I love the high driving position, it's easy to drive and gets up the steep hills easily. I can fit my road bike in the boot without removing wheels which is a bonus for me and can get luggage for a two weeks holiday in the boot without needing to drop ge back seats. All in all I have found it one of the most practicals cars I have owned and not found it's size to be a problem.
Its hard to imagine many other vehicles that could be as good an all rounder as the RX has been.
on top of that, he RX has run faultless.
My next cat decision, possibly next year will be the toughest as I'm either going to go completely impractical and buy a GS-F or else a new shape RX450.
Anyway, well done with your purchase and enjoy the ride.
