i think manual pedals would fit fine on the VX simply because the vx brake pedal is so freakin tiny.. .ive actually had a lot of trouble finding automatic brake pedals that fit on the vx

ive also got a few shots of the weathertech rain guards on my vx in my gallery, they are a very nice install especially when youve got tinted windows, i would def. recommend getting them from weathertech and not from a random online seller, i ordered mine from ebay and the passenger side one was a little defective, nothing a dremel couldnt fix, but still, i wouldve sent it back and gotten a replacement if i had ordered from them

i dont think that a larger moonroof/glass roof would be possible, the VX has a stuctural member that goes across the roof just behind the doors, i dont think you would want to cut through that, if you search other peoples galleries/posts for dynamat photos you will be able to see them
