Did the engine actually seize? To begin with, get a second opinion - from a Porsche Dealer. If the engine is beyond repair, you should consider replacing it with a used one. There are some shady engine shops, so be sure to check out (online) any one you consider buying from. Used engines come from vehicles that have been pretty much totaled otherwise. If you're selective and careful about this, you might end up with an engine that has less miles on Ford VCM II than the one your daughter ruined. Any way you look at this, it isn't going to be inexpensive.
