The plus four is a nice Mog and to be honest most of the time if were honest has more than enough power, However for not much more money second hand in the plus 6 you have two cars a plus four most of the time or supercar performance some of the time. It's worth having a test drive just to make sure the itch is scratched. I personally like the stance on the six and its been dry for two days of course you can use it as a daily no water ingress whatsoever.........
