I need some serious feedback on a 99 E320 4 Matic purchase, I spent an hour driving it and really fell in love my mechanic spotted more than usual rust on some bolts and differant places, is this car prone to rust I read this somewhere? The frame plugs were removed also but car was dry everwhere and was no sign of flood damage smell etc. He checked the faults codes and said they were numerous but they didn`t show while driving. I`D apreciate any opinions and feedback. Thanks this site is great!
