It sounds high, but they aren't Toyota Carrolas! Lots of these have been wrapped, some blown up and never resurected. etc.
Again, this is why I said it's an interesting question. Unanswerable unless there's a US-Canada DMV VIN data base to see how many are currently registered.
You know some that are built for the track that realistically can't be considered a Terminator by typical stadards, they are race cars with a termy body.
