Buy a Porsche.
In Gran Turismo, there was a plethora of R-35 GTR's to chose from, but... unfortunately, there was not an array of Porsches to really delve upon. You were restricted to a few offerings from RUF. Maybe that is clouding your decision?
In the real world, Porsches don't break, whereas... GTR's do. Porsches are build to be thrashed - they are built for motorsport. Spend your $180-190K on a low km GT3 or 911 Turbo. Further, think about all the slarts you'll get! There's a lot I would rather spend my 200 large on, and it is surely not something that comes equipped with a Nissan badge as standard.
