Whether it's a Ferrari, Porsche or Morgan, none of them really benefit from extended periods of inactivity. The only real difference to distinguish between them is how much it costs to sort them out when they need work. Porsche air cooled engines were pretty reliable, but since the introduction of water cooling they seem to have experienced more than their fair share of problems.
Lamborghini's by comparison seem to be able to get their owners to part with vast sums of money over simple things like replacement clutches that come about with too regular a frequency.
A good friend had 2 Ferrari's in his garage and gave up on them for Bentley's which also burn holes in your pocket with amazing frequency.
