Besides the porsche, i have a 2000 Jaguar XJR and a 2000 Dodge Dakota 5.9 QuadCab. I am in the process of ridding myself of the Jaguar and the Dodge and looking at Audi S4s, MB 500Es and MLs. I'd love to have more cars than 2 and a truck, but the garage thing simply won't allow it. If i had a larger garage, i'd probably have about 4-5 cars:

993 Cab
993 TTS
500E
Some kind of SUV or Wagon for utilitarianism (ie ML55 or E320 Wagen)
Some kind of touring/commuter (mileage) car. (ie Audi S4 or M5)

(i guess i am a german at heart)

haha, i could quickly add more to the list, but that's about where i stand currently.
