I think it depends on how long you can wait until you would need another car.
Yeah, you can potentially lose little to none in depreciation (or gain in some situations) selling your car currently. If you have another car or just don't need one, can be quite nice to get great value + reduce your insurance/gas etc. But if you will need another car again in 12 months I think it's a bit unclear whether it's worth it & where the market will be (granted - i'm no market analyst). If it's no issue to wait 24+ months I definitely think it's an amazing time to sell cars that get little use.
