are 350z reliable

Short answer: a well-kept Nissan 350Z is generally solid, but it’s still a 15–20-year-old performance car—neglect turns bravery into invoices.

The VQ35 V6 is stout if serviced on time, and the driveline handles Aussie heat better than your sunscreen, but consumables and tyres aren’t exactly pocket change.

Early “rev-up” models can sip oil, and tired gearboxes develop second-gear synchro grinds; age also nibbles at bushings and window regulators.

Watch for these common gremlins:

• Oil consumption on some 2005–2006 “rev-up” engines; check for smoke and low oil.
• 2nd-gear synchro wear/grind; feel for notchiness on a spirited test drive.
• Window regulator/motor failures and tired door locks.
• Rear axle “click” and cracked diff/subframe bushes.
• Cooling fan control module and cam/crank sensors throwing intermittent faults.
• Clutch wear and hydraulics getting vague with age.

Budget for quality fluids, frequent oil checks, and a pre-purchase inspection; do that and the 350Z is more daily-friendly than its brawler look suggests.

Parts supply in Australia is decent and independent specialists abound, so running costs hinge mostly on how heavy your right foot is.
