They also didn't accept the gasket in the oil pan was a problem.

Fortunately they agreed to fully refund me, so I've now handed the car back.

Sadly for me, this is probably the end of the 370z train. I don't want to take a risk on another 370z that will have this gasket failure issue, and there are no 2014+ ones for sale near me.
