Steve and his company Rivsu are as legit as they come.
Sounds like the customer assumed parts and labor inclusive when he was told price of parts PLUS labor.
Now if you paid for a proper manual conversion and it wasn't done correctly, that is another issue. But if you refuse to bring the car back to Rivsu to fix any issues you may be having with the car, then you really have nothing else to complain about.
I'll be looking to buy a GT-R in the future and Rivsu is where I will go!
