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.
