People ask me what it's like to drive old preserved buses - they ask if it's hard. I say no, it's different. Double-declutching is second nature once you've learned. In fact on buses with sychromesh gearboxes it's still a good idea to double-declutch as it reduces wear on the gearbox's sychronising cones.Never driven buses at all but I remember the local buses growing up had manual gears and I think double clutches before they went fully automatic.
The idea of double clutches to me sounds complicated but to someone used to it, it’s probably easy?
Going from a different angle, as far as passengers were concerned the Nation 2 took some beating, never a rattle and decent heating.
