The thing is, we have no idea what actually happened. It appears that the OP has at least some corroborating evidence of inappropriate treatment of his vehicle, starting with the mileage discrepancy and also possible interior wear/damage. However, we have no idea how that happened, who did it, under what circumstances it occurred, etc. Pointing any fingers, whether at Tesla blaming them for a deliberate cover-up, or at the OP for making up a story is premature.
The OP stated that the car was picked up by a flatbed, delivered to a service center that was out of state (Michigan to Ohio), worked on, then returned to him. There are multiple parties involved in the transport and handling of the car, and multiple opportunities for someone not involved with Tesla to get a hold of the car.
To me, the mileage discrepancy is the biggest corroborating indicator of impropriety on someone's part. 158 miles is excessive for a test drive or confirmation of proper operation. It indicates to me that a person not working on behalf of Tesla (although not necessarily a non-Tesla employee) drove the car for personal reasons, which is enough wrongdoing to warrant compensation.
