I don't think the tow bar is a dealbreaker in scandinavia but I agree that the choice of tow bar fitting with prying open some plastic cover is kind of odd for a $50k or even more expensive car if even a freakin' VW Golf has a swing out tow bar nowadays.
My rather frugal brother who's an IT-consultant and earns fairly well believe it or not, is starting to consider cars for when he's going to replace his pre-owned ~2012 CNG VW Passat station wagon
(that has a towbar). He has a wife and a five year old son. He wants a car that he can haul a lot of stuff with. And he would have been interested in a pre-owned Model S, if not for the fact that it can not be had with a towbar in Sweden... He thinks the 3 is too impractical since it's rear hatch i so small. He's considering a used X though. And perhaps also a new Y.
A towbar is a dealbreaker for him.
My father replaced his 2012 CNG VW Passat station wagon (t
hat had a towbar) early last year with a 3. He had been ill in cancer and was in his early seventies. He wanted to get a 3 fast. And I guess yolo was a considerable part of that...
He would have gotten a towbar if it had been available, if for no other reason than it would have been a really huge plus when it comes time to sell it. It wasn't available at the time though, and for him getting the car fast rather than wait for the towbar to become an option was more important.
I replaced my 2012 CNG VW Passat station wagon
with a towbar in 2018 (for various reasons...).
Getting a towbar on my new car was a dealbreaker.
But that is generally not a problem in Sweden since EVERY pre-owned car has a towbar!... And so did of course the pre-owned ~2015 CNG Golf station wagon that I ended up getting...
I actually do think that
a towbar almost always is a dealbreaker in Sweden and also in Norway...
In Sweden a Models S has always been a roughly 100K+ USD car... Those folks in Sweden can often afford to rent some other vehicle (or arrange some other solution) if they need to haul a bunch of stuff, but many other people here do not want that hassel. They want a car with a towbar.
And almost all other cars except the Model S has one over here.
