I will second on not getting the retro radios. Of course, it depends on what you want/need out of your car's audio system but in general, those retro radios tend to be mediocre sound and performance quality and reliability. I think they are "ok" but in my opinion they are certainly overpriced.
Most are made in the far east and rather cheaply made. There are some made with quality in the USA but most are not worth it.
