I'd have bought one but general opinion is that morgans are only for those who can't afford a Ferrari..............
I, momentarily, did the maths on a 599 instead of the Supersport but I couldn't get the numbers to stack up. If you buy a Ferrari you want something new enough to be covered by Ferrari's more recent service/warranty packs - ideally constantly extended in order to minimise costs.
I was discouraged from owning an Aston Martin by a former owner who paid out 6,000chf for the front brakes on a DB9. Having had the Alpina brakes replaced before I bought the car with original items costing 2,400chf I may have inadvertently ended up in the same place!!
