Thank you Steve, this is my first Lexus, 07 IS 220d-l. Nice car, just took it for a little run to Devon from Durham and managed and average of 47,6 mpg. A lot better than I expected given some of the threads in the forums.
Many thanks Steve. I've not got into the swing of things just yet as I have only had my RX300 for a couple of weeks. It is a september 2003 registration but appears, according to specs., a 2004 model?
