Are there cycles in the Tesla aftermarket?

I was in the market for M3 and was looking for a LR 2018/2019 models. About 2 months ago i easily find multiple people trying to sell theirs 38-42k. Even had some people decline my offer for 37k and came back with interest after lowering their price. Best deal i found was 36k in Chicago from someone moving out of country.

I decided to just order a new one but searched again out of interest if I could fine a killer deal. However now the aftermarket is completely consumed. All cars on Carguru, carvana, carmax etc... are pending sale. In other markets like cragislist, offer up, ebaymotors, price is now 39.9k-45k for a LR 2018 M3. No one willing to budge.

Im thinking it could be because of Tax returns, gas prices, new dogecoin millionaires? Anyone have insight?
