Hello John
Probably not apples for apples!! Last year I imported an older Morgan from UK to Aust. so did a tally up of all those costs and applied them to a later model car.
Allon White in UK are showing a 2014 4/4 on their website for 32,950 quid which currently converts at around AUD $60,000. Making a few assumptions and adding all the shipping and import costs that I had plus GST, customs and port charges on arrival takes it up to around $78,000, so I would say you are probably ballpark in your thinking about the pricing. (That $78K figure doesn't include the luxury car tax which, if you were able to import, might just be nudging the threshold and add some more to the costs!! Currently you would struggle to get import approval for a 2011 car I believe unless you had been living and owned the car in UK before bringing it out here.)
Best of luck with your sale.
