Look, you can't compare a Toyota and a Civic with an A8. They are as different a type of car as trying to compare the taste of lighter fluid with that of a fresh strawberry... That said, take it from me that Audis are known for electrical gremlins. Our family was a big VW and Audi family for a long time. They had more electrical issues than most any other car we owned. Windows, dash issues, lights, motor, etc. They are well known for that thing in the years around the one you are looking at. Just 411... My opinion is that you should buy a BMW if you want a luxury sedan like that. A8s are not sports cars by any means, but are great performance sedans. Great torque down low, but I am a solid BMW fan and my parents have had nothing but GREAT things go on with their BMWs since they left Audi. Just be careful, but for $11k, it sounds like a good deal. The regular stuff is pretty normal. Oil changes, the occasional part here and there - pretty par for the course. They are very dependable motors and will last a long time. The chassis is great, too... Now things like tires, suspension mods, exhausts, etc. are pretty high for that car... But, it isn't a dime a dozen Civic, either...
