Sweet! Glad someone saved it from being turned into something it shouldn't be
Looks like the door was replaced. When the cars were repainted before the CHP sold them on their car lot, generally the door tags were taped off, and door jams left unsanded before paint(unit # readable). The CHP office auto tech where the car served most likely put the reflective tape on the replacement door, pretty sure it was something every CHP vehicle had to have.
My dad has a twin to this car. You can see it in one of the recent threads I have posted.
What are your plans in the long run? You can't find out where a vehicle served unless you have the unit number or the plate(last four digits are the same), then only hope the assignment card still exists.
Can you run VINs on Carfax? Pretty sure you can... I have a 92 GT that needs to be run if thats ok?
You don't find many as nice as the one you bought, especially with the "CHP Repaint"
