Hey there.
I personally visited Koons last month to view a different diesel they had on the lot. They feigned ignorance of a pre-purchase inspection being a common request and I'm sure they knew whatever I found would be a deal killer. Somebody is likely regretting their purchase.
I built a program that found my diesel and provided great comps that helped me knock my price down by $4k. I was ready to fly somewhere and road trip it back. I luckily found a great diesel at Tyson's Porsche. I'm growing it into a potential "purchase consultant application" for people with more money than time. My current setup is focused on Cayenne. I'm offering to help you gratis as a way to help hone my program with real use cases.
Here's a
rough output example showing my scoring system and how I'm pulling from PCNA build sheets. Let me know if you're interested.
