We managed 19mpg today over a period of one and a half hours stop start in a deluge aiir con on and demist. We were a bit moist getting in to be fair but one hell of a traffic jam. The roof worked very well in horrible conditions however droplets from under the dash was not expected a bit worrying actually with all the electronic gizmos. Those with autos is it best to put in neutral or park in a jam can't bring myself to leave in drive. Em
