You're only allowed to drive one car for the rest of your life. What will you choose?
You're not allowed to drive any other vehicle during this time, whether you own it or not. Assume you have a fully comprehensive, lifetime warranty on your new vehicle; if the vehicle dies, your hypothetical insurance company will replace it. Essentially, neither the price of the vehicle nor its parts are a factor in your selection.
You'd want something with sporting aspirations, given that it's the only thing you'll be able to drive. However, you'll eventually have kids if you don't already, so that F40 won't really work out. Or will it? The choice is yours. Hypothetically.
I have a feeling most of you would just pick supercars anyway. But what about the eventual dings and scratches that come with long term ownership of a car? The constant worry of leaving it parked on the street? The threat of people stealing parts off it, or worse, the whole car? Single digit gas milage? Constantly getting pulled over? Think harder Opponauts!
