My first Lexus and it's brilliant! It's the most comfortable, relaxing car I've owned (and the most expensive!). I'd wondered about the RX but dismissed it initially as to expensive to buy and run but I started to read the reviews and realised that it might be a viable option. I've had my car for 3 months now and covered just over 3,000 miles of mixed driving from the dales of Yorkshire, to city streets. My driving style has totally changed,; I still keep up with traffic and overtake as usual but the Lexus just makes me feel far more relaxed and calm. But occasionally I let the V6 sing. I couldn't believe it the first time I used kick down, I referred to it as all hell let loose! Smooth but very quick for such a big car. It's really comforting to know that when you go past a slower moving vehicle you won't be in the outside lane for long. I've averaged a real 38.7 with a best of 45.1 I find the mpg indicator to be fairly accurate and within 1 mpg of the actual. Everybody who gets in the car says it feels like they are royalty it's definitely a great place to be regardless of the length of the journey.
I've got lots of questions to ask but have already found the answers to many of them on the forum so thank you fellow Lexus owners.
