Registration & WOF

Insurance$2,345

Insurance cover:

Scaled from the NZ average comprehensive premium ($1,311/year) against this listing's $79,990 price.

Unscheduled repairs$403

What breaks between services — an estimate by vehicle age (5 years old) and a brand-tier multiplier (budget-reliable/mainstream/premium/exotic) for Audi. 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 79,289km is well above the ~60,000km expected for its age, so the estimate is scaled up 20%.
