Hi all,
I have a Black 220 SE +MM with 13k (and counting) on the ODO. We cover 100 miles per day, 2 x 40 mile runs on the motorway at 75 - 80mph, and some round the doors stuff. The best we have seen is 37mpg, and the overall mpg is 35. This is a whole lot better than when the car had anything up to 7 of 8 k on the clock.
Cant say i have noticed a better performance, but have now got a rattly dashboard (Lexus have tried twice to fix it) and even a squeaky drivers seat (my wife and i only drive the car and together we weigh less than 21 stone)
Cant stop thinking about the 320 M sport i had test drove...... but would miss the toys.
