Good Price and Recommendation

My wife and I just purchased a used 2021 Sienna LE with 69,500 miles on it for $28,000. It’s in great condition, and we’re happy with it; no accidents, one personal owner, clean bill of health. What I want to know is whether or not it was a great deal. I feel that it was, and maybe that’s all that matters here, but I couldn‘t find anything cheaper for this year in our area (Western NY).

Additionally, the dealership is recommending I get an extended warranty for the car with Ally for the next 36 months/36000 miles. It’s a bit more expensive than I would like to pay, but I would appreciate knowing if there are any common failures that this would save me heartache on. It covers everything except for brakes, pads, rotors, wheels (the standard wear and tear)

Any help and feedback would be greatly appreciated! Thanks!
