Rob,
Long time....
Don't sell, you'll regret it, and I understang what you're going through, I have 3 year old twin boys.
I will never let my car go unless it's for a different model. It's about time management; when there napping hit the garage, when they go to bed hit the garage.
I have a truck for transporting everyone and winters, but my 911 is a daily driver the rest of the year.
You know how fast you can get diapers when you run out if your in the 911
And yes even 3 year olds can say Daddies Porsche...
Good luck with your choice....
