Got to love the knowledge on here!!
I have only ever lost the SVX once and that was on the Old Pacific Highway and was really pushing it - but a three dimensional aspect change (uphill, camber to the left and turn to the right) at speed, after just coming out of a reverse turn, was too much for physics to be ignored and ....yeeeeeeee haaaaaa...as the back stepped out.
I managed to catch it, and was poo-pooing myself at the time ("my insurance!") but now I look back and with each recollection, I am sure that a minor step out has become a tyre-shredding powerslide of Tiff Needell proportions!!
Overall, a ridiculously grippy car!
