Purchased a 2012 535i with 25k miles and also bought a 4/80k warranty the dealer offered from Z Series (CNA National Warranty). It is the Automotive Preferred care package and from looking at the contract it covers a lot and reads great but we know how most of those companies are. Any feedback or experience in this company or policy? I have 30 days if i want to cancel to get a full refund and I know I can go to Route 66 or others if this is not a good company. Thanks in advance.
