I'm definitley picturing the 4O7 as a shrunken 6O7
Bu in Italy these cars are extremely common- only FIATs are seen more than Pugs.
However- Peugeot should be able to sell a Top of the line V6 SE 6O7 in the US for about US$40,000- this is the price they are sold for in New Zealand- which I believe is cheaper than in France- however- the rising New Zealand dollar has made the 6O7 price in New Zealand look pretty standard in todays world. In fact the NZ and Australian prices are now about even. Also they get the 4O6 Coupe V6 for about US$35,000- so there is definite potential for cheaper prices- however we must keep in mind that NZ has no import tarrifs as opposed to the US.
I reckon that one thing they could do is make a boring 3O7 sedan for the US market- it'd be a surefire hit- if you see how the Civic has done over there (Where you can get it as a Sedan or Coupe)
