Any private party that is in the market that knows what that car is, knows its the same as a "regular" model 3 performance, except missing some add ons that a model 3 performance has (smaller tires, different brakes). Will that person who knows what it is pay more for the exact same car minus some stuff they could take off anyway?
I doubt it.
Any private party that is in the market that doesnt know about that particular car, would have to be convinced that "yes its actually a real performance model, even though it doesnt have X and Y".
Would someone pay extra for that car, even after being convinced its actually a legit model, just missing tires, brakes, etc?
I doubt it.
There isnt anything about that model that would make someone want to pay a premium for that car, unless it has free unlimited supercharging thats transferrable to them or something, at least that I see. At best it would be "similar" pricing to a regular model 3 performance.
More likely that it would be a little bit less than a model 3 performance, unless there are a bunch of bolt on specific upgrades that some enthusiast type might be willing to pay extra for. Not ceramic coating, or window tint, for example, but a good aftermarket suspension from a known respected brand, aftermarket wheels from a known respected brand, things like a nice rear diffuser etc.
No one is going to pay market price for all that stuff if its on there, but it might make someone pay, like $1.5 to $2 grand extra for like 6-8 grand worth of upgrades (not called FSD).
