no, sony's products are not built with quality in mind. try to find an Alpine, Clarion, Pioneer premier. besides that, it is a used sony.
i have seen a bunch of my friends with sony decks have nothing but problems. the one you mentioned is their top of the line model if i'm not mistaken(at least on CF it is), but it is used and it is still an Xplod.
sony has a failure rate about equal to the French Army. Don't waste your money. Just do a search on "sony sucks" and you'll get plenty of answers to your question since about a billion people have already asked the same thing in here and been answered.
besides that, it is a used sony.
