What happened to the Houston Auto Show?

I went for the first time in about 8 years yesterday, I remember every manufacturer was on the showroom floor. This year I lost count of brands that weren’t there. No Alfa Romeo, BMW, Mercedes, Cadillac, or Acura just to name a few.

While dodge/Jeep/Chrysler had test drives outside they didn’t have anything on the showroom floor.

Was this due to the nationwide weather or just the event dropping the ball?
