How much should I claim in diminished value?

A Geico customer hit my passenger door as he was trying to change lanes. The accident causes damage of $3,000+. It will take 2 weeks to fix.

My car is a red Ford Mustang ecoboost 2017 with 35k miles on it. It was in perfect condition before the accident, both mechanical and cosmetic. I have had the car for a month ago two weeks.

I check the Kelly Blue book for value in perfect condition and its says around 19-20k trade in value and when I add the accident it's went all the way to 15-17k. I'm thinking the car has lost at least 3-5k in value due to the accident. And I'm thinking of filling a DV claim of 5k.

Where do I start? Call Geico or speak to my adjuster about? Advice needed. Thanks in advance. Ask if you want to know more. Picture included. BTW, they had to replace the front bumper as well.

Does not matter name of other insurance.
does not matter the color of your car.
Does not matter the mileage.
does not matter how many minutes you owned it.

Insurance does not care what Kelly says it is worth.
Claim whatever you want.
Insurance lawyers will drag it out and only pay what they have to not some magic amount that pleases you.

Insurance will offer something. You accept or you do not.
You have insurance on your car. Your insurance lawyers should be doing this for you. That is what you paid your insurance premium for. Of course your insurance will do nothing if you decide to do it on your own.

TALK TO YOUR AGENT you have already paid for his service when you purchased insurance.

In my own experience, if you are able to get DV, it's not much, usually less than $1000. But you should certainly try.

Claim whatever you want but I doubt you will receive a cent for "diminished value". Why not? Because the cars value has not been diminished due to the door ding.

There's no valid claim for diminished value. Any body shop can do repairs to restore the vehicle

You don't talk to Geico insurance. Notify your own insurance company about the accident, and they'll do your talking for you. The insurance company will decide what your car's worth - not you.
Regardless of what you think you car's worth, the insurance company is going to pay you no more than the amount of Collison coverage you carry, less the deductible, for repairs.
If the car was going to be totaled, you might be able to negotiate for the Blue Book value. But, they're not going to total it - they're going to pay to repair it.

You can claim any amount you want, but you're not going to collect anything. Diminished value is impossible to prove, and you can't be compensated unless you can prove what you lost.

Yes I know, prior accidents do diminish a vehicle's value. Even piddly little accidents like the one you had, if a buyer knows about them, will make a used car less desirable to the uninformed public. But you still can't claim compensation for it, and here's why.

Insurance only covers losses that can be proven, and it's always the claimant's job (the claimant is you) to prove how much was lost. In order to claim diminished value, you'll have to know a) exactly when your vehicle will be sold, b) exactly how much the highest bidder will pay you for it and c) exactly how much more that buyer would have paid if this one accident had not happened. And you will need documented proof for all of the above.

Does that sound kind of totally impossible to you? That's why you won't be paid for diminished value. Courts and insurance companies don't pay you for maybe-probably losses that might happen in the future.
