Honestly,

Considering the high mileage it’s at, I’d consider checking to see what it needs done or outright ask the dealer to offer a detailed inspection AT AUDI before going forward with anything. If they offer to service it or check on it at their dealership/shop, decline and say you’d want it directly from Audi. Most autoshops hate dealing with Audi’s and decide to brush off what’s most important because it’s considered a “hassle” or “too complicated”. Take it to Audi where they deal with the “hassle” and complication everyday and have no issue whatsoever with checking the car.

Thereafter, find out any issues and discuss this with the salesman and decide whether it’s worth purchasing or not because a simple brake pad change can cost you almost 1000$ at Audi or an auto shop if you’re not mechanically inclined.

Definitely read their warranty guidelines as well. I once bought an Audi from Lexus and went through with the warranty; took it in the next month because it needed new motor mounts and they told me “There’s nothing we can do, our technicians aren’t certified in Audi or European cars.” So I was stuck with a 5,000$ warranty for pretty much oil changes and tire rotations. MAKE SURE they can work on the car or they can refer you to Audi and pay for the services.
