MrNut85 seems to be having some faith in Shields Sole Dart 34611, Been on late night boards on the 17/18 for most the past week.
Though is there a reason behind this? Just because a E200 is more fuel Efficient than a Dart so is a bit strange to have running a late on board. Is it the same board from the morning? As the Dart or a MAN E200 normally pass my house around 7am on 18s. Always seems to have a different vehicle on that certain board compared to the standard integral E200
