Hi Robcmar, we only picked it up on Monday and it has not had much use yet, but very pleased with it so far. Something like 55mpg at the mo but that's over less than 100 miles so not a valid test, I expect it to improve when she goes back to work in September. I do want to get some kind of MP3 player attachment but have not looked into it yet, the transmitter type would be good. I don't know if one exists that will take power from the accessory socket and then charge the MP3 player thru the USB? Ours is a Cachet, we were going for the Rhytum but the dealer could not find the colour we wanted so he took the hit on the difference between the Rythumn and Cachet (about £150 for the alloy wheels) markTime
