I used to have a pretty nice 911sc, carrera wing, custom factory color and such. So, of course, had to have my die cast collection. There wasn't much in the way of stock 911's, so started collecting racing 911s which were, for me, the GT1. Must have had somewhere around twenty or so, mostly from UT as they did lots of racing Porsches.
Sold most of them after got rid of my 911, but kept one or two, including my favorite the orange and white Giesse car #17 (M. Collard, driver):

I have owned this car for 12 or so years. It has been carefully stored in the top of one of my closets to protect it. At one point, I expected to purchase another 911, newer and possibly turbo but my wife doesn't like Porsches so I never displayed them. Now that I have the Viper, I am more in need of space for my kid's stuff and no longer have need to keep it.
Here is a link that shows one of the real team cars:

The other one I still have is one of the Mobil 1 GT1's.
