This ^^ and I would also ask them for a copy and take a photo of their driving licence, if you are that concerned you can always get a cheap dash cam with an interior camera and record the test drive as well
don't let them test drive with out you, you would be surprised how many let people go for a solo ๐ฑ
Check the hub face on your wheels, most have gaps where the nuts on the spacers can fit, so you might not need to do anything, my old Rays worked like that with 20mm spacers

I just saw the prices for Canada ........
We only have the 3.0 Supra here, which starts at $70k CAD base, the cheapest Stang is $32k CAD, with V8's starting at $46K CAD. It will be a tough market here if you include the other muscle cars as well.
