When you buy a car from us (and I'm sure most anyone) now, you have to sign that you were offered warranties, protections, etc. and chose to decline them.
It's because in our current legal environment, any time a person has serious problems with a car and call a lawyer, the first question the lawyer asks is,"Were you offered an extended warranty?"
It seems that lawyers have proven that if we don't offer extended warranties to everyone, we are discriminating against those who aren't offered them. If their cars break down, then it's our fault for not offering them and we can be held liable and be forced to fix the car.
The ironic side is that it's turned into an amazing sales tool. We HAVE to do it, but also get to tell customers they HAVE to sign that they were offered and refused. It makes many who wouldn't have purchased rethink it.
Doesn't surprise me at all that you would have to initial or sign that you declined.
