Well, having the coin to buy the car is one thing. Cost of ownership is another. So I presume you are suggesting we have more money for other options. Honestly there are way too many options to choose from.
If however I was to indulge in my childhood fantasies....
i think about this every time i buy a lotto ticket. what i'd do is buy a 911 turbo (or a variant) and drive it around the country to various tracks for like a year. stop at different places along the way. throw some winter tires on for the snow. imo it's the best DD supercar
then of course while i'm out i'd be having a garage built to house all of the other cars i'd buy
