The latest update on what has turned into a nightmare saga with State Farm (the at-fault party's insurance), is that they made an initial estimate of $14,059 which didn't seem at all realistic, just based on a common-sense view of the damage.
That then gave the Lexus body shop the authorization to do their supplement (or completed estimate). They came up with an estimate of $23.265 - over $9K increase, which sounded more correct to me, although admittedly just my view based on a guess...
State Farm then decided they needed to go out and re-review the car and the estimate. Then they (SF) come up with an estimate of $18,971. So I am now fighting with SF over how they take a reliable body shop's estimate and cut it by $4300! They are totally giving me the run-around.
I had SF insurance myself for probably 26 years of my life and always found them to be good to work with. But they are putting the screws to us, for an accident that wasn't our fault.
I'll let you know what happens next, when it does! Sheesh, this stinks!
