alright so im planning on making an automotive purchase pretty soon and i am looking at audi A4 or S4. my dad currently has an A6 with the 2.7t engine which i really like but im lookin for something a little smaller. any thoughts on like a b5 A4 vs S4? an S4 would be pretty pimp but i dont reall know anything about their reliability etc. im looking to spend less than 20k any help would be rad thanks!
