Another thing people haven't noticed is that the Scania chassis comes with a higher powered 6.7L Cummins ISBe option, It produces only 10hp less than the highest rated Scania ( Which is 280hp ) and produces near the same torque as the Scania, Despite being 2 litres less than the Scania.
Id heavily suggest getting the Scania Chassis E400MMC on trial before making decisions on what to buy.
It still won't be as suited to running up and down the A19 every day as a coach, as coaches are literally built for that purpose.
Of course there are obvious drawbacks to operating coaches on the TTX especially if you factor in cost, but coaches would also last far longer on the route than your Scania powered E400. Bear in mind here that the route has killed a fleet of B9TLs in 4 and a bit years.
I'm pretty sure the coach v bus debate has been had many times before, especially when on the subject of the TTX, however now there are increasingly fewer buses that are capable of running such a route, whereas there are several options in terms of suitable coaches.
