Oh good point. I have a Boxster. I'll edit to make that more obvious.First, congrats on the most unusual post I've seen on a forum. Without the post count I'd assuming this was some weird trolling.
Second, Boxster or Cayman will make a difference.
Third, don't the side rails on those fold down? IOW you don't need a box that size, but instead the collapsed dimensions which I thankfully do not have a test model for. Yet. I'm pretty sure it would fit on rear deck of Cayman but would damn sure want it secured somehow. I'd give it a try at a local dealer!
Lastly, won't it be incredibly hard for someone who needs this to get in, let alone out, of this car?
That unit is similar to my mom's. With the wheels off, it stowed diagonally in the frunk.
This is why my Mother-In-Law will never see the Cayman. If we could get her in, I have doubts about getting her out. Not to mention, you can fit me, the wife and the MIL in the Cayman. I hadn't even considered if the walker could fit.Lastly, won't it be incredibly hard for someone who needs this to get in, let alone out, of this car?
