Spot on Peter. It may be one of the non compliant ones so should have had the rear springs replaced already (and may be the fronts). Most in NSW, Victoria and W.A. have been done by now.
2011 was the period when Morgan had poor quality rear springs so check ground clearance under the gearbox crossmember. 195/65 R15 tyres will give you 10mm more. A change of tyres should be considered just for the age anyway.
