Speaking of preparing for future market, don't forget BMW has also been planning ahead with the other strategy, going under 30k.

Maybe Porsche better consider either vastly improving the interior luxury or the powerplant if they want to keep the Boxster spot secure. Performance was one of the key reasons I didn't consider a Miata or Solstice. But to see beefy turbo versions now with 250, 300 hp for ~30k including a bimmer, the Boxster might have a tough time at 60....
