About 3 years ago!

Max is mostly just pleather seats. Almost always refurbished. Was originally long distance limited stop, but the limited stop thing fell by the wayside, even though the X numbers stuck (eg Durham X46, Darlo X services.

Sapphire is long distance with pleather seats and WiFi and occasionally working sockets or usb uharging points.

Frequents is frequent town services eg Durham 64, which is every 10 minutes through its core.
