The Slongshot is the exact opposite in design to the M3W.
Why should all people have the same taste?
I could imagine that some Slingshot owners would not drive a M3W even if given free to them.

Lots of sport car fans consider the Mogs to be very strange and outdated too.
Would be a very boring world if everyone would have the same taste.
