Mystery Machine

Never bought a used vehicle....thought it was too chancy Found a reasonable price on a used Pontiac Montana van real fancy Had a few quirks and they made it all right She ran real fine for a few months then came the alarm lights One then two audible and flashing the oil was dangerously low Checked the oil and it was full; I new this machine was gonna cost me some dough!! Drove to the dealer and traded it for a Lemona A brand new set of problems in the Sienna
