Flash the ECU? Lol wow for a battery change? That sounds like a hey over voltage might occur because of poor wiring...smh no I understand with the BMWs Audis and Lexus' so I can agree with you on that. It seems like a nightmare that I would not want to want to deal with. so that answers my original question thanks
I guess seeing how the 370z is still new to people one doesn't know the maintenance problems that might occur but in fairness not a lot is expensive the most part is buying an overhauled engine for 4500 in later years which to me is better than buying another $40k vehicle. But then again I can see the extras on tires lines an breaks are up there too. So either way you gain or lose good call though
