Has anyone here purchased an extended warranty through AutoXcel? I got a quote through my local Audi dealer (Audi Marin) for 5 years/60k miles of coverage for $4875. Salesman said it was "full coverage" which seems a bit too good to be true. For context i have a 2016 S6 with 97k miles. I'd like to buy the warranty but don't want to be left with denied claims, repairs etc.

If anyone has had a good experience with another 3rd party warranty provider let me know, thanks!
