Not many, aside from the obvious. They're too mass produced.
I reckon the BRZ86 has a decent chance in about 30 years, assuming they don't do a successor. Think about it: A relatively light 2+2 RWD coupe, with a revvy engine and excellent fuel consumption. In the future of turbochargers and higher fuel costs and everything either FWD for cost or 4WD 'cos no one can drive for toffee, I reckon they'll be quite desirable.
