Thinking of purchasing first Audi
If you have to pay to have it worked on, you will be poor. If you work on it yourself, your studies will suffer, but you will acquire skills which might keep you from working at McDonalds after you graduate.
Make sure you have a garage stocked with lots of metric tools. Buy a VCDS for diagnosis.
Have lots of cash in the bank for emergencies. Have good credit for the times when you will be renting a car to get to school.
All cars have problems. Some, like Audis, have expensive problems. Some, like Toyota and Honda, have relatively cheap problems.
However, you probably have lot's of responsibilities and demands if you are a full time student (I am a college professor in the sciences), so the last thing you need is a troublesome car with expensive problems. The trouble with all German cars is that they are very expensive to repair, complicated and relatively DIY unfriendly (although I remain a dedicated DIY-er).
The mileage on the A6 suggests a timing chain replacement is near as are other rather expensive maintenance - think $3k+
As much as I would love to suggest that its a great choice, I am afraid my suggestion is think Japanese…
One consideration to have is the option of leasing new. My daughter has done two VW leases and they are so cheap. If you think a $7K used car - that's nearly all the cost of three year lease (with warrantee, high reliability, etc). Insurance will be more, but so will piece of mind.
Good luck - keep us posted :-)

-The C6 3.2 is known for carbon build-up on the valves which if it hasn't been done, it's due for it. That will be at least a few hundred dollars for a cleaning job.
-At that mileage, I'd want to make sure the transmission fluid has already been changed (otherwise I'd walk away completely).
-Suspension bushings, engine mounts, and shocks (are they worn or in good shape). Mine were destroyed at 75k miles.

If you try and fix it yourself there just isn't much info out there with detailed instructions. Get a BMW instead, tons of help compared to an Audi. I have a 2001 A6 with only 115K on engine and I am ready to set it on fire!
Bringing Audi to Life for Audi Fans

Okay, here are my thoughts. It is true that maintaining an Audi can be expensive. But if you are lucky enough, you can end up with a car free of problems which can be exceptionally reliable for its age and mileage. My case.
The first thing to consider is the price. If it's too low, there must be something wrong. Skip.
Second, request a CARFAX and study it thoroughly.
Three, request to have it checked by a professional.
Fourth, drive it yourself on a long enough distance and make your decision.
Fifth, like any other used cars with no warranty, after the purchase, have money spared in case something goes bad.
Sixth, if you want to keep it problem free for a long time, and have less breakdowns, drive it gracefully.
Seventh, come here often and learn about the car.
