I am very happy with the performance of my bog standard Plus 8, have revved it to six a few times , and seen 132mph (on Mulsanne straight playing with a French Plus 4 Supersport) But I feel their happy place is lolloping along in the countryside. In fact I am amazed how revvy the standard 3.9 is compared to the old Holden and Ford V8's I knew from years ago.
