Where: real world
Searched: pages for various manufacturers on Google, and some company web sites.
My MC, /noveau riche/, has decided to buy a sports car. While they could, without flinching, write a check for a Lamborghini, or a Spyker, or even a Bugatti Veyron (and the insurance that goes with it), that's far more conspicuous consumption than they really want. (They've also taken a couple of high-performance/defensive driving courses.)
On the other hand, a Mustang or a Corvette or the usual run of Porsches and Ferraris is too, well, common.
So let's suppose a convertible, with a nice interior and accessories, and a price of US $150,000-200,000.
What brands and models are they looking at?
