Over the years, I have bought ext. warranties on some vehicles and not on others.....most of the time never used them, a couple a times it did indeed pay off......here's my question: I have never explored GM extended factory warranties.....do any of you have any advice on the buy process? Will dealers offer competitive pricing? My dealer's financial guy of course has already presented me the MSRP figures for various plans.....but with my recent Mercedes, I found the factory warranties could be bought from ANY dealer.....and there were some who were willing to bring the price down considerably! What's the experience in Caddy world? Thanks.....!
