Big congrats 370er
.
I only picked mine up yesterday (I was lucky dealer had one in stock). I personally didn't get the protection stuff for a couple of reasons and AK, has mentioned one of them.
As I also dont think it's worth it for what the dealer chargers for it. Plus for us in Aus at least it carries the 30% LCT as the cars are already over the threshold. Also I personally believe IMHO you can get much better jobs done and cheaper, by going aftermarket.
Lastly if you look after the car and use good car cleaning products/waxes it will keep your car just as well looked after. It also looks like there is a few of us trading/selling STI/WRX's for the 370Z.
BTW You will love when you first get I guarantee it.
