Welcome to GenVibe. You definitely did get the better end of the deal! As far as a mess interior wise ... I can certainly relate to that
My son's Blue 09 Vibe GT in my signature, had goo, suckers, spilled sugary beverages, brown stuff, etc. all over the interior and we ended up gutting the car to remove everything down to the steel uni-body and clean it thoroughly. It was a dealer trade in OR a repo car for all I know! The bright side was that we got a one year old car for $13,100 at the time. It just needed a S H I T load of work done to it. Keep this Vibe for many years to come and enjoy the ride
