Seized engine repairs for A5

My 2009 Audi A5 has done about 85,000 km and has had major oil consumption since 60,000 km. It's not that long ago that I had to spend about $7,500 on multiple problems (starter motor, timing belt, head shaving etc.) and within 100-200km the engine has now seized. I am told I need to replace the engine, but where does it leave me. Can anyone shed some light on this problem?
