Hmm, the only 328 props stored are US-certified examples. For reasons I do not remember, they require a rather expensive and time-consuming refit for operations in Europe. German Cirrus Airlines that wants to replace its Dash 8 fleet with further D328s consequently has found it quite difficult to source suitable aircraft. However, the reason why they have pursued with their plan is indeed the relatively low capital costs that come along with the Dornier 328.
If I have it correct, Scot has seven aircraft. Two are leased out. DND-LCY requires one aircraft, EDI-LCY 1,5-2 aircraft. SOU-AMS kept another one busy. So we more or less have now two instead of one aircraft permanently available for charters.
