Hi I'm Donald and you can assume that I'm a mechanic. It's one of my greatest pains but best joys! I also own a 2003 Cadillac Deville with the 4.6 northstar Engine. I'm also an auto Mechanic! I just can't think of a better trade to have than one that allows you to test the limits with your northstar. When it breaks it's going to need LOTS of the best deserved attention and I DO GIVE my Devil...
Replaced 5 (twice on driver side) window regulators. Plastic parts on something used almost daily? Constant o2 codes. 80k miles. Drives great but too many repairs.
