Are the Works of Jane Austen suitable for a 13 yr old at a very high reading level?

I was assigned Pride and Prejudice as reading when I was 13. Most of the people in my class seemed to understand it fairly well, though there are aspects to it that probably take a more sophisticated reader to appreciate. I have known other people who read it at that age and dearly loved it. For my part, I found it unspeakably dull and nearly impossible to read. In my early days, and living in the Midwest, I was a Tom Sawyer and Huckleberry Finn sort of guy, and I wanted that sort of adventure. It took quite a few years for me to get back to it, and now it is probably my favorite book.

There is nothing in Jane Austen's work that would be considered inappropriate for a 13 year old by most English speaking people. There are the elopements of Lydia Bennet and Maria Bertram, but their treatment is reasonable for a person of that age, even from the point of view of most people of strict religious leanings.
