may be no help but a perspective from a pssenger point of view
A hotel I stay at used to pick us up from airport in an A8 or 7 series, they now use Superbs which are much more comfortable
with a soon to be 3 yr old and a wife to taxi about on day trips when we get chance so comfort is a factor,
hopefully my wife will also get her driving licence this year which means i might get the chance to be in the passenger seat.
