,,,Should i be suspicious about that ??
Yes, you should.
To clear up suspicion, Tesla should clearly post on the web the reasons:
Some reasons may not have anything to do with the car quality:
1) failed to finance
2) prospective owner didn't make it (as in pass away and the estate didn't bother to complete the purchase)
3) owner changed their mind
4) no room for extra showroom display
Others might have something to do with quality:
1) Showroom display: Lots of people have been touching, climbing in, sitting in the car while the odometer remains static.
2) Test Drive car: unlikely in this case due to only 5 miles on the odometer
3) Loaner car: unlikely in this case due to only 5 miles on the odometer
3) Rejected by owner due to some kind of owner's own standard of quality check such panel gaps, paint...
4) Quality not acceptable by Tesla and now has been remedied (young intern backed the new car up and hit the pillar...)
So on and so on...
"New" here is a legal word which means it has been never registered which could actually be very old in real life due to encountering numerous people/drivers wear and tear as a displayed car, test drive car, loaner car...
