Welcome to the forum. Nice bonus getting those AMG wheels. I found the forum a few months after buying my first Crossfire. It has a great bunch of knowledgeable members. Even with a car with that few miles you can still have a few minor problems that are easily resolved with information on this site.
My wife and I were born and raised in Michigan north of Detroit. I know how the winter salt can really rust up a car. It's fortunate you found one with low miles and garage kept.
I also have a red roadster. It's a garage queen with around 13k on it. I'm not a fan of the stock wheels and am glad with the SE it has SRT look alike wheels, but with dark gray between the spokes.
