Default SC400 engine noise question
I noticed when I'm cruising on hwy say at 65mph there's a humming engine noise. It's not bad and barely notice it with radio or music on but I thought these cars are suppose to be dead quiet. Other SC4 drivers have experience with this? Maybe I have a slight exhaust leak somewhere?
