The P6 is a tag wider, those few extra CM's can make a difference
My P6 as the original hood which stores lower to the body so is not intrusive and the main reason I did not buy a later model.
The P6 is without question is wider and I dont feel the hood mechanism on the earlier cars, must admit haven't sat in the later version. must try that for hood clearance. Tthere's just so much more choice in the P4 market
