But if you can show things such as recent new parts, tires, batteries, tune-ups, etc., sometimes you can negotiate more than the original offer. Way back in 1974, my wife was rear ended in our little Opel Cadet that we also towed behind the motorhome. Repairs just slighly exceeded book value of the car. The other driver's insurance wanted to total it. I wanted it fixed (a used car suitable for towing behind a motorhome isn't always easy to find), so when I told them about the low miles, new tires and battery, etc. they agreed to pay for the repairs. And when our teenaged daughter totalled a car in 1981, the insurance company agreed to pay more when I showed them the receipts for the parts for the recent brake job I'd done, new tires, etc. Now when my wife totalled one in 1999 with 121k miles on the odometer . . . well, I wouldn't have even considered selling that car for what the insurance company said they figured it was worth and what they wanted to pay. However, I didn't quarrel at all because I thought their initial offer was quite fair considering what the car was actually worth.
