I'm sitting on a 10 year old SV8 VY that has been a spectacular vehicle.
I had a replacement gasket seal on the right side of the rear wing and within the three years a driver side B-pillar plastic cover where the top clip snapped.
These were the only warranty items that I had, and were only picked up by the final examination by the Holden dealership in North Ryde, which was good of them.
Other than that, a power steering unit, a rear set of rotors and a single set of tyres, it's been all good.
I get the car services at 10K and apart from wiper blades and headlights ( I run them 24x7 ) that's about it.
So as far as reliable, I'd put it up against any car on the planet. Worst case, I've got a low coolant coming up on the dash which is the result of a cracked overflow bottle that never seems to require refilling. It's being doing that for 6 months and the temp gauge never goes past 2/3. Yes I"ve checked and it doesn't ever completely empty so one day I'll fill it.
So here we are 10 years on and the VF looks like a decent trade, bring it on!
