I have since cutting that out put a small piece across the 2 front halfs just in front of the steering wheel platform as I was planning on pivoting the steering platform up for access as well.
I have also altered the shape of 'armrest' pieces since too to give a more sporty feel to it.

A spoiler type bit on the back would be nice but I'm trying to keep this fitted on a 2440x1220 sheet and it just barely fits now.

I did have a high nose version of the front half drawn up too but my mate just wants the low nose version, I might do the high nose version later for myself.
