Buying a Used Tesla Model S in NZ: What to Check

The Model S occupies a strange spot in the NZ used market — genuinely quick, still impressively capable by current standards, but old enough on early examples that buyers need to go in with realistic expectations about long-term ownership costs.

Which era to consider

2013–2016 (original body, pre-facelift): Now the cheapest way into a Model S, at $38,000–$55,000 depending on battery size (60/70/85 kWh) and condition. These are the highest-risk purchases in the range — early build quality issues, first-generation Autopilot hardware that's now obsolete for software updates, and batteries approaching or past a decade old.

2016–2020 (facelifted, revised front end): $56,000–$78,000. Improved build quality, later Autopilot hardware, and generally better documented service history through Tesla NZ.

2021–present (refreshed interior, yoke or standard wheel options): $85,000–$135,000+ depending on Plaid or Long Range spec. These carry the most remaining warranty and current-generation reliability.

Battery health is the single biggest factor

Model S batteries have generally proven durable — many original packs are still in service well past 250,000 km — but capacity loss varies a lot depending on charging history. On an early 85 kWh car, we'd expect 75–85% capacity retention at 150,000–200,000 km with reasonable charging habits; cars that were fast-charged heavily or routinely left at 100% can sit meaningfully lower.

Always request an independent battery diagnostic before buying. A capacity and cell-balance test costs $180–$280 and is the single best money you'll spend in the buying process — it can reveal a pack needing attention that would otherwise cost $16,000–$24,000 to replace outright.

Known problem areas by era

• Door handle mechanisms (all years) — the flush electric handles can fail to present, particularly in cold weather; replacement per handle runs $300–$450
• Air suspension (fitted to many models) — compressor and air spring failures become more common past 100,000 km; a full corner repair runs $900–$1,600
• MCU1 infotainment (2012–2018 cars) — the original media control unit can become slow or unresponsive as its eMMC storage wears; an upgraded MCU2 retrofit costs $2,800–$3,800 but substantially improves usability and resale appeal
• 12V battery — same story as other Teslas; budget $320–$750 depending on whether your car has the lead-acid or lithium-ion low-voltage battery

What to check before buying

• Independent battery capacity and health test
• Air suspension operation at all four corners, including compressor cycling behaviour
• Door handle function on all four doors
• MCU responsiveness and boot time
• Full service history, ideally with Tesla NZ service centre records
• Remaining battery and drivetrain warranty (typically 8 years / 240,000 km on Model S, though check the specific build sheet)

Running costs to budget for

Item	Typical cost
Annual service/inspection	$220–$380
Tyre replacement (full set)	$1,300–$2,000
Air suspension corner repair (if needed)	$900–$1,600
12V battery replacement (if needed)	$320–$750

Our recommendation

For most buyers, a 2016–2020 facelifted Model S represents the best value point — meaningfully improved over the original body style, with enough remaining battery life and warranty coverage to make ownership predictable. Earlier 2013–2015 cars can be excellent value if you find one with a well-documented battery health report and are comfortable budgeting for air suspension and MCU attention over time. Always get an independent pre-purchase inspection rather than relying on the seller's word on battery condition — it's the one area where guesswork gets expensive.
