Well after a bit of searching and a few suggestions to remove the spare wheel and strip my bike down to component parts - i tried getting my bike into the back of the Z.
Well all i had to do was remove the seat post, pedals and wheels - taking all of 10 seconds ..... and .... Ta DA !!
The only bit removed from the Z was the little boot cover bit that sits at the bottom of the rear windscreen.
So proof after all - as if it were needed - that the 350Z is practical too !
54" Specialized road bike.
FACT !
