yeah mate, my olds owned a new BMW540i V8 at one stage, and at 164 000 everything was tight and smooth. No rattles etc. I was expecting this from my 55000 SS. Was never going to get it!
On the positive, spend some time driving a holden V6 (VX, VY) every now and then which is what I do. I know that every time you get back in that beauty SV8 of yours, the GenIII will tickle you pink. I think the VY is a massive improvement over the VX especially in looks, but that Gen3 is sweet if you look after it!
Here's to you winning many a traffic-light-drag with your new SV8!
