Depending on the extent of the rust you may need a parts car.
Other agencies would often tag onto the CHP contract some with minor differences. Sometimes these agencies would get car right off the CHP lot.
CHP normaly auctioned the cars at 75000 miles, sometime agencies would buy used CHP cars with less miles.
I'm assuming Marin got new cars
Would be cool to see this car done in its original colors and equipment.
