Alphard 2.4 or Alphard 3.0?
If you intend to take the 2.4, might as well you take the Starex. You'll appreciate the extra torque it has from the CRDI engine to haul the whole bulk.
Furthermore its new, and you have 5 years warranty as opposed to a recon Alphard which some dealers offers 1 year to no warranty at all.
