Do I have any other recourse against the driver to get a new car?

As far as property damage goes, you are only entitled to the book value of your car because it was totalled. I assume you have been paid this. You cannot then ask for a new car. In the eyes of the law, you have been reimbursed and paid in full. However, you mentioned being out of work for a year and a half. You did not indicate if this was related to the accident or not. If you were injured from the accident, you may have a claim for pain and suffering against the at fault driver.
