Sometimes I do kind of wish I had gotten the 401A; it would be nice to have a memory spot for easy ingress/egress, and maybe BLIS. But honestly, in my driving position, the blind spots aren't bad, and I couldn't care less about the Shaker upgrade, so it wasn't really worth it to me, either.
401A actually does the auto seat move for easy ingress/egress. I â‚©drive an F-150 as my winter vehicle so I'm used to using integrated mirrors to check blind spots. The shaker pro is a waste. Even the stock exhaust was fun to listen to and I'm installing my FRPP Sport cat-back as soon as I pull the car from its winter slumber tomorrow! Stereo will be even more worthless!
The shaker pro has negative utility for me - I wouldnt chose 401 simply because of the Shaker (ex: if 401 was a no cost option). I doubt it sounds much better than the Shaker I have (which is ok, not great) and it weighs more and takes valuable trunk space. I do like the rain sensing wipers and memory seats, but no big deal.
