This youtuber is probably the best one I have seen regarding depreciation of F Types and other sports cars.

 

^^^ that was from over a year ago and he did a new video a few weeks ago:

 

Car gurus has a pretty neat price tracker. Below you can see the price trends by year, 90, 30, for F-Types. I would imagine the sample size of sales is so small that a couple of lowball sales, or overpriced sales, would skew the overall for that year. Unfortunately they don’t break the cars into the sub models of V8, V6, etc. The overall index for all used cars is at the top. Some F types track better or worse than average.

Pickups and SUVs remain hot.

 

Cargurus price trends are based on sale listings not actual sale figures so the average would be a little harder to skew.

 

I should have used the term "listings" vs "sales" in my post.

I would image that actual average sales prices would be even lower - if negotiated, (excluding tax, tag, etc) Still some insight into trends . . .

 

Not really, many dealers list for serval thousands under market value and include wordings like "exclude down payment of xxxx and fees of xxxx".

 

Used cars in general went up for awhile in Kelley BB. Shortage of new cars was explanation. No new no trades.
