The seller may have an open title from the time he bought it, so there wouldn't be any records in Texas yet. This ARIZONA car with its different options from regular AzDPS cars sure is a mystery in regards to who originally used it. It reminds me of the 1985 "CALIFORNIA" SSP Mustangs that were not CHP. Perhaps this 1986 SSP was state owned originally versus being AzDPS? Or maybe AzDPS used it for non-patrol purposes?
Bobby has had great success with getting documentation from the GSP. Maybe we should turn him loose on AzDPS to see what he can find?
