Agree, 6 test drive vehicles sounds pretty excessive. I went to my local center for a test drive too, I was literally the only non employee there. I dunno how many demo vehicles they had but I hope not every center gets 6 of a model, they sure didn’t need multiples when I went!
I did kinda want to take a Model S for a spin, especially if they had a Plaid. But then I didn’t want to ruin myself either. So I didn’t ask.
I totally get them wanting to prioritize repeat customers, as I think is fitting to do as a reward for loyalty.
