We've been down to my wife's car since May when I sold my x3 to carvana.
It hasn't been a problem except for a few times and then this weekend we both had pressing things to take care of and we were having a hard time abiding by the schedule of "car share"... we almost divorced
Luckily my brother is finance manager at a dealership which has a huge network of brands and we have other close friends and family who are GM's or Managers at various dealerships and they've all been throwing offers at us to try to get us to buy anything but tesla... so we're not worried about paying an inflated price... it all comes down to finding something we think we'll enjoy as much as the tesla.
