Hello, I am looking at a new 09 SRT8. I may purchase it tomorrow? My question is the car has 6 miles on it and its sitting outside. When I looked at the engine the aluminum parts appeared to have a slight corosion on them. Can this be cleaned off to make the engine look better. I plan on keeping it stored inside. Why would a brand new engine have that on it already? Did anyone else have this on their engine?
