Guidance on extended warranty / Audi care

Looking for a gut check. I purchased a 2021 e-tron PP about a month ago and am looking into buying an extended warranty. The car has 33k miles and I drive very little. I would expect to put on 5k-7.5k miles per year.

I received a preliminary estimate of $3500 for a 3 year warranty and $4500 for a 4 year warranty with $250 deductible. I also received an estimate of $1100 for the 50k and 60k mile services.

Some questions:

• do these prices seem fair?
• are they negotiable?
• anything I should specifically ask about?

Thanks in advance.
