I think you may have answered your own question, if your questioning whether the car, just sitting there gives you joy.
Now my Z, been modified more for track then street. Which means its a bit of a pain to drive on the street. But I sit get a thrill driving it when I take it out. Still gets lots of comments on it. So the excitement for my Z is still there. Also my GF likes riding it.
My Z is also in the garage till March, but every time I go into the garage, its like, well I need to start on prep for next track season, clean the Z up and get it ready.
So its what your heart/gut tells you what to do. Just think long about it, for if you read the forums here, there is seller remorse at times..
Good luck --
