There are alot of right hand corners in NZ.....
To be honest based on my experiences - mechanical failure can happen anytime anywhere, whether its owner neglect, or a poor production batch **** happens when it wants to happen.
I will enjoy my TRD Aurion anyway I want, and not live in fear of a mechanical failure - If the car breaks it breaks and I will repair it or upgrade it.
There are over 500 TRD Aurion's out there and many more Lotus Exige S and Evora S with the same setup. I haven't noticed a huge recall on either vehicles and most people believe the 2GR-FE is pretty solid.
