No but I used http://www.ican2000.com/dvfaqs.html

I've been through two accidents with my previous M3's and won diminished value awards both times. I live in CA. The insurance company low balled me and only offered about 25% of what I got by going to small claims court ~$5k. This guy will give you a wholesale and retail DM via mail. He outlines the DM algorithm used. I used this for 1 of my estimates for the judge and he was ok with it. I also had a dealer BMW dealer estimate. Don't go to CarMax etc...

The insurance co. must make you whole by law. It's a bit of work, file forms, got to court etc..but worth it. The insurance co don't have much of a leg to stand on and judges are pretty sympatric to your situation so will give you top $.


Good luck. Hope this helps...

 

Got my baby back on Friday Dec. 23. Including the supplemental damage, the total bill came out to $12k. I called the other driver's insurance company to inquire about a DV claim. I literally had to explain what DV is to the agent. (You can't make this up...) And so begins the upward fight to be made whole. :-(

Thanks for the link, sf911c2. I'll check them out, too. I have a feeling I'm going to be following in Telum's shoes and needing a lot of documentation.

 

St Lucie Appraisal is the company that calls Porsche dealers in your area and obtains the expert opinions of six sales managers as a basis for their diminished value report. To my knowledge nobody else goes to these lengths to arrive at real world DV amounts. The rest of the independent appraisers use formulas, some of them refer to them as algorithms, they are supposedly super secret proprietary methods but all just a version of Rule 17C. Then there are those appraisers who just produce a figure out of thin air based on their years of experience. Insurance companies know the real deal from a BS appraisal and will treat you accordingly.

 

UPDATE: I received my diminished value report back from St. Lucie. I have to say pretty thorough. As Curly_Sue mentioned, it includes quotes back from six Aston Martin dealerships comparing my car to a hypothetical equivalent car with an untarnished history. Lowest hit = 12.50% and highest = 17.86%. I just submitted the report to the other guy's insurance company. We'll see what they have to say...
