I'm anticipating a purchase (some vintage of pre-restart 182, but immaterial to this topic) next spring, and most of what I'm seeing out there are not yet upgraded to ADS-B. I assume this is because the owners don't wish to dump $6-7k into a $40-50k airplane just to keep it legal, and I can understand that, but it's also some leverage for me hopefully as it's a major expense that will happen within 24 months.
I also see optimistically high-priced older aircraft with ADS-B, though usually with many more things modernized and reflected in the price. The avionics delta at that point is so large that I'm having a hard time figuring out what the ADS-B piece of that alone should do to the price.
For those buying planes right now, do you use lack of ADS-B to drive the price down a bit more, or are today's typical prices reflective of that already? I'm thinking that while the owner may not want to drop several grand on the plane and eat it on the sale, I don't really wish to either, so there should at least be some sort of middle ground to be had unless it's already a smoking deal. Am I way off base?
For my price range this is really the only modern upgrade I'm weighing into the equation this way. Everything else is more in the generic "works / doesn't work" category for negotiation purposes.
Thanks for the responses in advance!
