I stuck with Honda and now Acura because everything is so familiar between models. Pretty much all the placement of the major controls and functions are similar to my 06 TSX, 08 RDX Tech, 11 MDX Adv, 18 RLX hybrid, and 19 MDX Adv hybrid. It doesn't take long to learn the extra features added over time. I can see how the features and functions on an Acura would take some time to get use to if you drive multiple brands. I'm always comparing the previous gen or trim levels against each other compared to comparing other brands against Acura (3rd Gen MDX Adv -vs- 4th Gen MDX Tech or Adv).
