I calculated the same costs (tires, batteries, oil changes, repairs, etc) for my '86 Volvo 740 Turbo. I bought it new and kept it for 18 1/2 years and 285,000 Km. I was quite busy at the time so I had all of the maintenance done by a non-dealer specialty shop. It was our only vehicle for about half that time.
It averaged just over $1100/year. Expensive, but too bad for a european car I kept for a very long time and could have taken anywhere. We did take it on a 6000 Km trip when it was 9 or 10 years old and were taking it regularly on 4000 Km trips when it was 13 years old. It also looked good, rode well, and handled well (for a Volvo anyway).
