Being a Porsche fan I would choose the new Porsche Cayman GT4.    400 plus HP.   0-62  3.1 sec.   0-100 less than 9 sec.    Mid engine, 6 cyl. opposed.    $170,000   Expensive sports car for the street or economical race car.    Be a great track car as well.     One car I would keep, if I got some of those already posted that are 100 of thousands or more, just sell them and buy a good street car, track car, fun car.
