More to do with the fact that the current stock is too old for the Oxford LEZ. The current E400's are heading to Hemel Hempstead for use on service 320 to Rickmansworth, alongside new Streetlites on service 100/101 Luton - Stevenage.
MAX is a concept designed by North East & Yorkshire to improve inter-urban routes. It will soon become standard across longer distance routes I am sure, and it's already been adopted by Wales, Shires and I understand soon Midlands too. They're refurbishing existing stock but yes there will come a time when they're due to be replaced - certainly the Scanias on X26/X66 are 10 years old like you say and are well past their best.
The new engineering director is starting to get to make his mark on the fleet too, of course the state of the fleet has been improved drastically over the last year or so. I am hoping that we can start repainting existing stock that needs it - some of the S-reg Darts and Prestiges lasted their whole lives on their original coat of paint!
I think the purchase of the Volvo B9TL's is a good view into the future... purchasing vehicles specifically for routes rather than a "one size fits all" approach, as in the past. Using Darts on the 213/214 from new is an example of previous wrong purchases, they were never designed to do work like that so its no wonder they were absolutely knackered at the end.
Lets hope the Sapphire Implementation Team have a say in which vehicles to use/buy for Sapphire branded routes.
