Welcome to the forum. Several factors determine how good of a buy this ST is. Cost, mileage and maintenace logs. Looks like a used police vehicle which means it could have been well maintained or drove really hard. I'm not too good on used vehicles. Most of mine I purchased new. But being retired from law enforcement after 44 yrs of service I know how some officers can beat a vehicle into the ground or take care of it like it was his own. Did the department have a take home care program or was it ran 24/7.
