Is this a deal? 2001 S4

Found this 2001 used S4 while searching the web. Looks to be a good deal - super low miles - only 16,713. Anything I should watch out for as far as
engine and mechanical issues? Thanks in Advance. TAIL&VEHICLE_KEY%5:6618&LOT_ID%5&CLASSIFICATION_DESC=Sedan&LISTING_TYPE_DESC=Used%20Vehicle&PERSISTENT_LISTING_TYPES=YES&LISTING_TYPE_DESC=Used+Vehicle&
