All great replies. Particularly McLovin—who hits all the issues.
I've owned Porsches for about 30 years, and for me they represent a combination of practicality and sportiness that is unmatched in any other car. And it's that combination which is so attractive, and breeds the loyalty to the marque.
I did own a very gorgeous Ferrari Dino once, and of all the cars I regret selling, I regret selling this one the most. It had a feminine delicacy and voluptuousness about it that was utterly intoxicating. No Porsche could match it for the passion it evoked.
But ultimately it was toy, rather than a practical car. I didn't drive it hard—at least not very hard. I didn't track it. I would never take a long tour in it. I avoided rain like the plague. I was always glad when it was back in the garage without incident. I didn't dare wrench on it. And I did throw vast amounts of money at it. But sweet jesus was it a lovely machine!
I have always heard that 348's are the absolute dogs of the Ferrari world. Handle like crap. Built like crap. Don't go near them. The 456's are luxo-barges—and pretty far away from the Ferrari DNA. Not sure why you would buy one of these when you could buy a true exotic like a Porsche 928 for far less

.
But whenever you go from a Porsche to a Ferrari you lose the element of practicality. And that can lead to buyers remorse very, very quickly—unless, as someone said, money is no object.
