Agree with above. That is a lot of miles for that vehicle. Your going to struggle with the maintenence if you spend too much on the car.

 

am i going to get a lot of troubles with a 4.2L with around 100k miles? I work full-time in summers and usually get around 3-4k.. how much dollars in repairs am i gonna be looking at? and what is a good amount of miles to be looking for in an a6 (4.2 or 2.7T)

 

Lots of money, you need to stay on top of these cars. The oil is very important. full synthetic every 3-4k mi really try to stay towereds 3 Also with the high miles. if it were abused and not allowed to heat/cool the turbos could go and that is not cheap at all. But it is tough to say. the car could have been babied its entire life and could go for more then another 100k mi. 3-4k a year wont get it done on a 4.2 or 2.7 (specialy the 2.7) when I was making that (2 years ago) I had my 2.8 and it ended up sitting a lot even when it needed something as little as an oil change because I didnt have the money. if you really want it, get it. just be careful all it takes is money though. I'm 18 now and just bought my first S4 and believe me Insurance comes into play with people our age. look into that before you buy. I now have to work 5 days a week 10-12 hours a day. but I geuss that is life now but I love these cars.

BTW I love my A6 2.7T and dont see why it wont go beyond 200k it now has 90k mi and runs like new. (bought with 70k mi) I have been lucky with maintnence and only done brakes and oil changes.

 

Tons of info on this and other forums on these questions.
Did you mention year? That will also be a variable when given the mileage. High miles/ few years typically means hwy versus street miles. Some think of that as better.
As a 4.2 owner, I like the simplicity of the v-8. It's virtually bulletproof and predictable. It may cost more in gas than the turbo, and both use more gas than other vehicles, particularly if you drive them the way they were meant to be driven. Keep that in mind as well in your budget as you not only will be filling it up more than some other cars, but all of these will require (and some will disagree and fine) more expensive (premium) gas. Likewise, synthetic oil is recommended on the higher mileage cars and that costs more as well. Also, you will not want to run cheap tires on this and given their performance nature, you will wear cheaper tires out faster etc., etc., etc. These are just the routine costs. Audis, just like other "nice cars" as you put it, cost more to repair than others.
I do not mean to discourage you as we all like Audi (most) owners. However, at 19, use everything else, particularly the free stuff, you have going for you (youth for instance) to build and maintain your image. Impress people with who you are, not what you drive. Likewise, bank some of the money and let it grow. In the long run, it's more impressive (if that is the need here) than cars, and with more money, you will get more car. If you have the money and can afford it fine, but if not, don't start your adult life off with an unnecessary financial strain. People will respect you a hell of lot more for making responsible decisions and you'll find your life a bit happier/easier. Then, reward your smarts with a great Audi a few years later. Nothing wrong, or nearly as sweet as satisfying a delayed gratification. Probably not what you were looking for but its advice given me that has not led me astray.

 

Railrunner is right on the spot with that advice man...There was another young guy recently who was asking the same questions.I gave him the same advice as above. Its the best your gonna get. BTW--the 4.2 is a more reliable motor but keep in mind that anything you buy with high mileage for little money is a warning sign. For 8-9K you could buy a pretty nice, pretty quick Japanese Car....Nissan Z or Acura CL (I had one, quick car) or a Mitsu 3000 GT. Look in the middle to late 90's. You will have little maintenance and the cars will run worry free. I had asimilar carand it ran me through college and 2 years after. Then,I bought my AUDI and money was never a question. Stay around the forum to learn as much as you can though so when you do buy you are prepared. Good Luck!

 

Just a note, I'm replacing the right side turbo on my car next week and its going to run about $3000. Also getting the 60K service at that time since they have to pull the engine to get to that turbo anyways. If you can get a warranty I would do itm I'm only having to pay $250 for the service. Cost of maintaining a 2.7t is relatively high according to most sources including Consumer Reports and Car and Driver. I do love mine though
