What does your mate plan on doing with it? I honestly don't understand the demand and high price that these cars are commanding. Our MY17 wagon is used as family car and is enjoyed. Are all these low km cars being put away in garages never to see the light of day? Are people buying them as investments? Was your mate able to get insurance close to the $80k mark? I was looking at getting a Redline or Motorsport a month ago. I could not get insurance for anywhere close to what sellers were willing to take for their cars ($10 to $20k less than what cars were being advertised for).
In the end I decided against purchasing a V8 Commodore and will get just get a Shelby GT-H Mustang or Supersnake instead (currently waiting to see what the new S650 platform brings).
I don't really know what he bought it for other than being a V8 Holden enthusiast for years and not owning one for 5 years. He had a 2013 VF1 SS wagon and traded it on a Jeep Grand Cherokee SRT in 2016, still has the Jeep. Personally I wouldn't buy a Commodore at todays prices and I'm appreciative of buying my Aug '17 Redline ute with 3900km's for 50k early August 2020 just before they went nuts. My V8 ute's a toy and my daily drive is a VF2 SV6 (work) ute. We paid 25k for the '16 SV6 with 44,000km's Oct 2020 before they went high to the high 30's /40k. Previous work ute was a BA XR6 Falcon I had for 10 years ending up 450,000km's on it.
My Redline ute is insured for market value they've got for 48k and that'll do for the $640 premium given that I paid 50k for it. I guess some may insure them for todays prices if you pay the premium for it. Above all else with insurance for me is choice of repairer so the car doesn't end up ruined with a crap panel job if it does get bent.
