Have to say I can't wait for ours to go but I am willing to bet I will miss them after a while, in a sadistic sort of way...!
I managed to drive 21104 and 21105 and while they were B10BLEs they weren't a patch on the ALX300 bodied ones. Quirky though, so something different. Not exactly practical though which one wheelchair/buggy bay and no kneeling suspension!

Edit: Suppose I better say my piece too!
I'm Scott, 24, been driving for 4 years for both Stagecoach and now Arriva at their respective Stockton depots, although I have spent time working out of other depots too at times! Been interested in transport all of my life since being very little and dad taking us out on the train for the day while mum was at work...

As you can probably tell I live in Stockton so tend to see most of what goes on in the Teesside area and also try to get out and about as much as I can, both around the North East and beyond (I'm travelling to Luton as I write this...!). I am quite lucky to have grown up knowing people in the industry and many of these are still great friends now, and I've also made friendships through this forum so I would advise anyone to keep posting and have a great time!
