CA does not allow the sale of any new diesel autos..so I guess this is only available to the select few who illegaly import them or buy used cars out of state.
CA blocks diesels due to the soot causing cancer.
Until that issue is cleared up..no more new diesels for CA.
Did you know that California has been below the national average for all cancer deaths for fifty years?
