NiceYou're not alone!
I've had my S197 GT for 15 years. She was always intended as a toy for going to meets and shows. After every journey she gets detailed and put away in the garage. I love to just go out to my garage and stare at her in all her shiny glory! She is known to family and friends as the Garage Queen and currently has just 21,000 miles on her.
I had various other cars, including some nice BMWs, as daily drivers. But they just never got under my skin. I decided I needed a Mustangs as a daily car, too. There was no way I was selling the Garage Queen to fund it, so it would need to be a cheaper alternative. For 4 years I drove a V6 SN95 as my daily, then upgraded to a V6 S197, which remains my daily to this day. It IS fantastic being able to have a Mustang I'm not quite so precious about, although I still give her a weekly bath to keep her looking her best. I'm English, and having a Mustang......or two(!) is pretty rare, much like you in Australia I assume.
But getting back to your point, I do get almost as much satisfaction from just owning it and looking at it as I do driving it! I guess it's like having a 1:1 scale model.........I collect enough smaller scale models to drive my wife mad, so having a bigger scale model in the garage is the next logical step
