Hell, I put close to 200,000 miles on my 1000 sedan over a 15 to 20 year period & the only problem I had was when it spat a fan blade at max RPM one afternoom.

A 10mm spanner allowed me to remove the damaged part & the remaining blades were left in place, so I was back in action within 10 minutes.

My stock 1200 coupe has just made a trip to Melbourne & back & I travel the 145k to Sydney at least once a week.

Provided that the car & its mechanicals are in sound condition & in good repair, then Datsun reliability is legendary.
