My dad used to let me clamber into his capri through the boot sometimes I used to think it was great fun
i've found the boot a usfull way to enter my car particually when the central locking stops working, dam thing!
my opinions on the 4door/more door thing is:
maybe it's said to make the 4door sound less like a shopping cart,
or, its still an escort, but with more doors than the popular sporty models, hense "more door"
get a capri or a fezz then there's no agruing over doors!
