I purchased mine from Warranty Direct. 7 years/70000 miles with their PowerWrap+ offering. At the time I bought it with $100 deductible it was $700. I checked with my dealer (Service Manager) and was advised they had dealt with Warranty Direct with no problems. The dealer wanted $1500 and it was third party coverage also.
