The GT3 Porsche has had very strong resale values approaching 90-100% of original msrp for 20 years and is still true for the last 5. Even the Carerra models have held 70-80% of their resale values for over 40 years. Of course, the GT3 is likely not driven as much with most examples accumulately only a couple thousand miles a year (Many on the track). I don't think GT3 resale values at or near original msrp is ever going to change.
