Open design car

how might this work economically?

it is said that the parts of the iPHONE and NEXUS ONE cost about 175 dollars perhaps....... the phone then RETAILS for 500

what if there was an open design car?

there is a 3000 retail car in INDIA TATA NANO.........

WHAT IF A CAR could cost.... 4000 dollars in the UNITED STATES?

how would that impact things?
