@Dustyvalentino I would not agree. Only very few types Strats appreciate in value such as selected limited Masterbuilt Signature Strats (SRV), Strats built by certain Master Builders (J. English, sometimes J. Cruz or maybe C. Fleming in Japan), vintage Strats. The appreciation of the MK Strat is an absolute mystery to me. No other factory built sig Strat appreciated. Perhaps the OLY white version of the Mayer kept value. The Brazilian RW SRVs built in 1992 increased, but these guitars were REALLY rare.
It is impossible for Strats to keep value because the Fender factory shells them out in spades. In fact, they have never been more affordable in such a quality (take a 2nd hand Custom Shop Strat for a hair above 2k Euro shortly before Corona happened). Corona increased demand a bit because of more people staying at home but this will normalize when the pandemic is over.
