Tbh, the E400s are solid as mentioned and can easily do high speeds. Also people need to look at the speed limiters on the streetdecks (50mph as most modern wrights I think was mentioned in a GNE thread) whereas Enviros get an easy 60/62. Tbh ADL have always had solid builds but alot of operators have been deterred from using them due to Brian souter (SC CEO) having shares and not wanting to give money to stagecoach (the old GNE MD done this apparently hence the lack of ADL) . Personally I think the ADLs are good where they are with arriva atm and when they do get replaced hopefully they're is more ADLs on the cards.
