IMO where the 185s score is in terns of leg room and the sound of the engine. In terms of sheer comfort, the seat on the 158 is quite unrivalled. I would even think of having one in my lounge. Fact is, I drive a Rover 75 and the seats on the 185 are not enough to tempt me out of my car full-time. Have you ever sat in the driver's seat on a 185, that is like a revelation, best seat on the train?
On a separate issue, is it really so necessary for the 185s to be so bright inside? You can se them half a mile off, so much light pollution.
Anyway, better shut up before the moderators start desecrating the thread in bold red ink, just that I have my own ideas on how the new stock should look.
