Absolutely, she should have been forced to make restitution for the two police cars she destroyed. As part of her sentence. My guess is $70,000 or so.
With all the equipment onboard and special paint job, it should have been more, plus a penalty. But at least this phillyvoice.com article says it was more than $70K:
"Blumenthal has been detained since her arrest and may be released in the coming months for time served. In addition to the prison sentence, she was ordered to pay more than $95,000 in restitution and must serve two years' probation."Unfortunately for any kind of permanent rehabilitation, the OP article says she will probably be out in a short while due to time served.
