I went to test drive a Silvia S15 this morning, Loved very Bit of it. Apart from one thing, i found there was not much head room when seated. This was the only downfall of hte car design for me, So i was wondering if this was a major issue or if people just adjust to it and sit differently, or if there is a work around for it, some how lower the seat or adjusting it to create more headroom.
