Re: How common are the reds?
Are you looking for a coupe or convertible?
I have 2 red/burgundy cars and 1 black one.
The Oyster (gold), new silver, and sapphire silver blue are probably the easiest colors to take care of, hide imperfections, etc.
As No Warning Shot mentioned, the SE roadster may suit you with its red color and SRT6 wheels (has cloth interior also).
They are great cars.
