If you want reliability, in all areas mechanical and electrical, buy a 5 - 10 year old Toyota. Don’t buy a new Toyota as I hear the wheels fall off the new ones
Jokes aside, all newish cars have lots of complex electronics within them. It’s something you can’t get away from if you want the higher levels of safety modern cars provide.
I‘d go VF unless you really prefer the looks of the VE which should also be cheaper to buy. Just take note that, IIRC, early VE V6‘s had issues with stretched chains which was supposedly sorted in the later VE’s and definitely in the VF’s. Whichever way you go, check the vehicle service history well as these engines need good clean oil else they suffer if service intervals are stretched or skipped.
Also keep in mind there are more protections if you buy from a car dealer as compared to buying from an auction or private. From a car dealer you have both an ACL statutory warranty
and a 3 month statutory used car warranty. With buying at auction or private you get no vehicle warranty other than any remaining factory warranty (if you buy one of the last of the VF’s which may have had a 7 year factory warranty).
You could always consider a ZB as they are supposed a good vehicle and the V6’s AWD quite a lot of car for the price (back in 2018/19. But that’s only if you can get over the commodore naming controversy that bothers some…
Ultimately the choice may end up being driven by budget constraint as you haven’t mentioned any $ figure your willing to spend.
Sadly now’s the worst time to be buying as used car prices are inflated because of new car supply issues. You may be surprised what a VZ wagon may cost these days so hopefully you did some price research before settlement if you had a market value insurance policy.
