Registration & WOF

Insurance$1,699

Insurance cover:

Scaled from the NZ average comprehensive premium ($1,311/year) against this listing's $41,990 price.

Unscheduled repairs$264

What breaks between services — an estimate by vehicle age (6 years old) and a brand-tier multiplier (budget-reliable/mainstream/premium/exotic) for Isuzu. Averaged across good years and bad — most years cost less than this, and an occasional big-ticket failure costs a lot more. This listing's 100,700km is well above the ~72,000km expected for its age, so the estimate is scaled up 20%.

Total annual running cost$6,840
