What is the expected life for an Audi A4?

I own an Audi A4 which I bought new in 2005. I am looking to write off it's depreciation using the straight line method and am wondering what the expected life of the car should be. Anyone know?|||Well it ALL depends on how the owner has taken care of the car...Assuming that the car was serviced properly, etc. Audi cars have been known to last a very long while


When I worked at Champion Audi, it was common to see some A4's come in with 200K+ miles on them...If you are trying to account for the cars depreciation, usually 5 years is the common approach...I mean you cannot really answer this question exactly|||Depends on how well you care for it. 200,000+ miles and 20 years is easily attainable. I've had late 80's model Porsche's with over 200K on the odometer that are still on the road with their current new owners.
