An oil change isn’t any different than any other vehicle on the road, Audis have a belly pan that needs to be removed to access the oil pan but that’s a 5 minute thing to do. Tires are tires, some use run flats. Brakes can get spendy depending on the model, some of the upper level cars use Brembo brake calipers and typically will dish out the rotors and require replacement rather than resurfacing them but that’s not unique to Audi. Other than filters I don’t see that keeping an Audi serviced would be a huge amount more than keeping any car in good running condition. Broken engine mounts can be expected at 50,000 miles or so but again not unique to Audi. There is the cost of taking it to the dealer for your service though, which is a good idea in my opinion because the techs know the cars very well. For dealer recommended services, always consult with the owners manual first before having anything done. Some services aren’t required but the dealers push them anyways to add to their bottom line, shocking huh?
Is the cost of ownership an issue when you’re considering a $100k sport sedan anyways? Lol
Fwiw, regarding Brembo brakes, Dodge Hellcats use them. They are serious pieces of hardware but there are drawbacks to performance. If you drive them like they were intended they will wear out the front pads and rotors in 10,000 miles. The problem here is the cost of pads and rotors, a pad kit is $400 and the composite rotors are about $1,000 each. So that’s a $3000 brake job haha. Seen it more than once when they get traded in. Add in another few grand when they need tires, and a few hundred more for a 10qt full synthetic oil change and you’ve got a car with 10k miles that needs $6000 worth of work before it hits the pre owned lot.
And then there’s that little thing with the microchips and lack of cars on dealers lots. Cars are very hard to buy right now so keep that in mind. The BMW dealer I drive by everyday seems to have a good inventory though, they (BMW) must have better connections for parts and materials than other manufacturers do. Crazy stuff going on in the car market.
