How many Ferraris does the Gaddafi family own?

I realize at the time I post this I may be writing about a family which is in flux, as they say, maybe running for their lives, but how many Ferraris and what models to the Gaddafis own?
I heard once the Col. had a 400 convertible and that he was even an investor in Fiat.
Here's a story from a British paper on his ner'do-well son making too much noise with his Ferrari:

Gaddafi Ferrari seized in Germany
12:01AM GMT 02 Jan 2008
German police have seized a Ferrari belonging to the son of the Libyan leader Muammar Gaddafi, saying its exhaust was too noisy.

Seif al-Arab, 25, who is registered as a student in Munich, watched as his £170,000 Ferrari 430 was loaded on to a lorry and driven away after being stopped by local police.

Officers claimed that they recorded 110.5 decibels from the sports car's exhaust system instead of the permitted 98 decibels.

The vehicle has been impounded and will be returned only when Col Gaddafi's son - one of seven - pledges to change the exhaust system and pays a £100 fine.

Police said that Seif al-Arab had been stopped and warned before.

His international licence was also thought to be invalid so he may have to take a German driving test.

Bild newspaper asked: "Is there one where people can take it in a Ferrari?"
