Not sure if a Saint Regis (M Body) counts. But the police had them here and had a 360 so guessed it was E58.
My buddy at the time did work on the cop cars. Needed a trans and other things so the depth let it go instead. He pulled the trans and was a great car. Fast for what it was. I was offered it, and I should have got it to keep miles off my E Body.
Be a fun car today and drove great on the interstate. My memory was had a mid 200 gear as was a state car ment for hwy use.
Had extra cooling and coolers. No lights. The ones you saw blacked out at night waiting for speeders on the I-10
Certified Speedo, light on A Pillar.
I am sure it could reel in a speeder with a E58 motor and 8 1/4 with 245 gears?
