I'm sorry to hear that u cannot drive a manual car due to reasons but yes the interior rear view mirror is differnt too...
trunk spoiler
quad exhaust
side molding <---- leave out cuz says M5
side mirrors
front air dam
wheels
rear window molding
interior rear view mirror
steering wheel
speedo/tako meter
seat is different and yes i think the spacing of the head rest is different so u cant just insert a M5 head rest into a 540 seat.
Ummm as for looks I cant think of any others at the moment.
Oh and yes obvious difference is the M5 badge. Are u going to put a M5 badge on there too? or leave the 540i badge? I say leave the 540i badge. Reason: people who know the car will be able to tell and know it doesnt come in a automatic transmission. people will call u a poser and such. I for one do not like to see M5 badge on a NON M5. I dont mind people modding it to look like a M5 as long as they keep the original badge on it.
