the good old days before airbags
i thought about gutting my interior but i decided it just wasnt worth it, especially with a 4door. i do have a few pounds less of sound proofing tar but aside from that my interior is pretty stock. automatic windows and mirrors i probably could take off a real big chunk by going manual...but it its a simple thing that should stay on all daily driven cars.
to get back on topic: a 2400lb. s2000 would be such a worthy investment. i would definitely get one.
