Current daily (VFII SV6) came from Muirs also and besides the terrible pre delivery job on the car, I've only made one warranty claim in the 100,000km life and that was a semi broken drivers seat back - the replacement is starting to do the same. But otherwise it's been great. It's now serviced where I bought my HSV (one of the Suttons dealerships) and they've always been great. However, the E3 HSV must have undergone $10,000-$15,000 worth of work under warranty, and like Rons, is awesome to me. But some of that comes from the engine mods I've had done in the last 6 months. But it won't ever see a Holden dealer again after the initial report from the workshop who did the mods, telling me of missing bolts, stripped bolts in many places in the engine bay and under the car. He bought my servicing that I can't do myself, which isn't much.
My sons 2018 Astra that sat in a panel shop for 14 weeks before it's return as they were waiting on parts to arrive from Holden. And it was all underneath suspension parts that were being waited on. They should have stolen them off the assembly line where ever they make them these days (hatch = Korea I think). They won't take any more money from my family either.
Shame. Their loss. Tesla just took our money for our next car, just late this month.
