I know how you feel. I used to live in the same town as them, and dropped by their location once to check it out. But still no SkyCar in my garage.
Surprisingly, it appears they still exist.
Yeah I read some article years ago saying they were embroiled in lawsuits. I am surprised they are still claiming the M400 is "in development" after this long. Sadly seems more of a long term money siphon than any real project.
