Same here on a M3P 18 months in and lost over £30K it’s not just Teslas similar story on my business partners Volvo EV. Recently sold my 992 911 three years on and £15K down and the dealer sold it for £500 under what I bought it for new. Everyone talks about how much cheaper EV,s are to run but in reality overall costs are horrific.
Not sure why it isn't is a good comparison it's still buying the same thing, a car? I am also not sure what lead times have to do with this you just need to be organised and Porsche lead-time depends very much on model and the lifecycle of that particular version.911 isn't a good comparison, how many of those are Porsche actually making a year? Anyone buying a 911 probably has a reasonably long lead time.
Unlike Porsche, Tesla have shown their hand which is that they are going to chase volume at all costs, even if it means reducing their sizeable margin. This is the flip side of the coin really - people champion how great it is that Tesla have got 25%+ margin across the cars, compared to their competitors who make single digits or even a loss, without thinking about how this might affect them.
To echo @UrbanSplash's point - I would not buy a new Tesla and assume it is going to retain an elevated value "because it's an EV", or whatever, not when Tesla could lop off another 10% at least and still be profitable.
Completely agree Tesla have pushed for volume which raises their profits due to scale as well as lower entry points to ownership. On the downside for owners prices have come down in the second hand market and will only get worse. I believe the model Y is due to out sell the Toyota Camry so you can see which direction that is heading in.
It's just like buying a mobile phone. My next one was bought via the app, I haven't had to deal with anyone not even on the trade in. I will go to a large out of town shopping centre and pick it up and to be honest I prefer it that way. Better than spending hours with the dealer trying to sell me stuff I don't need or want and some Business manager coming out and shaking my hand and saying thanks for the business behind gritted teeth because I have had to haggle the unclear pricing structure. My iPhone isn't worth much after a year either.
Tesla have won me over my M3P was way better then the Golf R we had, better built and better performance by a mile. The MYP I am about to pick up will be everything as a family we need lots of space, performance, great interface cheap for to fuel be it electric, however I know come trade in I will have my pants pulled down again, but I have accepted that.
