it's definitely worth it.......unless you mod your car and get denied.
I've used it before on other vehicles for anything from cracked flywheels to broken axles to complete engine replacement. Once you pass roughly 50% cost, ya good!!!
The nice thing about the warranty laws in this country is, they have to be able to prove that it was the upgraded/AM part that caused failure. Typically other that upgrade part isn't covered because its not OE, just my experience from being in the car business .
