If you don't have a ski pass you can make one pretty easily.
If you have a coupe, you can pry out the window enough to get some hook on the door handle and pull it open.
I don't know if you can fold down seats from the trunk if you do have split, folding seats.
Making a skipass isn't a big deal...search for it.
Upcoming NYC dates: Jan 8 and 27. See Facebook for other shows and PM me if you can make one...love to see you there!
Mangofy your E46!
