Lose the "bling bling" duct/foglight things on the front and try to make the four cylinder model less expensive than a comparably equipped Mustang or Camaro V6. (or the V6 less than a Camaro or Mustang V8)
And as far as the other concept, the "P-Nut", if they name a car like that after the bassist from 311, what's the Bootsie or Flea going to look like?
