....what would it be? Keep it to a present day animal, nothing extinct and post a pic of it if you can.
For me, I've always wanted to keep a Perentie Monitor Lizard (Varanus giganteus) but I doubt that will ever happen seeing how they can't be exported from Australia.
I think it would be cool to keep one of the Chinese Giant Salamander (Andrias davidianus) .Being a endangered species I highly doubt it ,but still just think of the little girl screams from your 6'4" buddies, everytime you feed it in front of them.
Oh, if I lived in a warm enough climate I would have ALL kinds of torts outside too I put mine out in the summer, but they only get about 4 months out. Try keeping a Sulcata indoors 8 months of the year!!! Not fun! Now imagine an Aladabra...
I second those Salamanders too, those things are wicked awesome. I would settle for a Hellbender, heck, I have always wanted to see one.
I'v always wanted australian snakenecked turtles...no real reason I couldn't get one I guess except for money and space. I'd also love to have a fly river turtle but I don't think there's any way I'll ever have the space.
