I find the seats very comfy but I know others say they are too stiff. I think as long as you get the adjustment right you'll be fine. The R32 is a great long distance cruiser IMO
Have a look for the "buyers guide" for a list of known probs with the MkIV R32.
Fuel wise you'll see around 28-30mpg on lond journeys, where as short blasts will return nearer 20mpg
