I would sell the Porsche for money and keep my Prius and buy another house. I drove a Camery sport while my car was in the garage and I put a months worth of fuel into it in 9 days. I'm totally over fast cars at this point in my life. I have what I need and is most practical so I am happy.
I was thinking the same thing, but then again... I want to drive sporty ones for daily use.
It's like asking what would you do if you win that Porsche at Casino. I'd sell it, use that money to invest to make more money.
