I have concerns about an online only sales model, especially in Australia. If you're in California, Norway etc where Teslas are everywhere then it might make sense but in emerging markets like Australia the average person will at the very least want to LOOK at the car and most likely want to test drive it first. It's a huge purchase, not a pair or shoes.
Us Tesla fans will happily order a $100K+ car sight unseen and undriven as we have seen them plenty of times but now that the Model 3 is going mainstream there will be many people who wouldn't have considered one until they saw it at Chadstone or Doncaster Westfield etc.
I personally have several friends who can easily afford a Tesla yet never even considered it UNTIL they ran into them at the Tesla galleries.
I have a strong feeling they will reverse this in the next 6-12months...while they may not reopen stores, they will I suspect at the very least start offering test drives via online bookings......they have to........there is NO WAY you can have a mass market car and be online only....
