No PI attorney worth his salt would give his client a "ballpark figure". It's not worth anything until someone's willing to settle or a jury renders a verdict. The OP doesn't give enough info to truly value it. For instance, where will the jury pool be drawn from? What does OP do for a living? What does the defendant do for a living? Does Defendant or OP look like a scumbag or upstanding citizen? Was anyone drinking? What kind of vehicles were the OP and the Defendant driving? Did the OP or the Defendant have political or otherwise offensive/divisive bumper stickers on their vehicles and did those stickers make it into the photos of the vehicle damage which might be introduced as evidence at a trial? I could think of about a hundred other questions such a this which will all factor in to what a jury might award which is the starting point where insurers determine what to pay. That being said though if there is no unusual factors present I would suggest that 3x past medicals plus 1.5x estimated future medicals would be a good guess.
