Bought an '07 Police package with Hemi, and 4K miles at police auction on Friday the 24th, with front end damage and got a clean title for $4K. It was hit pretty hard ( officer hit a guard rail @ 60) and looks like about $9K in parts only to fix. Should I do this, or just part it out? Motor/tranny seem fine. How much is a motor/tranny combo worth?
