rear seats, black leather with a smaller flying 'A' logo
i would retain the rear seats as it has comedy value when 4 people get out of such a 2 seater looking car.
this is only my personal view, but i would ditch the up swept tail pipe look.
how about coming out at a horizontal angle and then cut staight across the line of the bumper, sort of opposing one and other, if you know what i mean

keep up the great work.
