I am assuming you are buying it used from the dealer, or are the add-ons you are thinking of doing on your own?
If you are able to add things on from dealer/seller then I agree with ed,
yes chillax seats, yes plug n play is a must, yes wedge, yes swivel driver seat, yes on the tower mounted mirror/beer opener.
No flip up bolster. I am 5'7" and I do not need it, the bow is low and I have no problem seeing over it when getting on plane.
No swivel racks, standard are fine and saves you $500. I ordered with standard racks and have been searching for nice swivel racks, finding them everywhere for 1/3 the cost of the axis swivels. Also, the plug n play can be made by buying the parts from
www.wakemakers.com for less than the "plug n play" option from the factory BUT, you will have to figure out every part you need and install it yourself. I think that option is only $250-300 or around there.
anyhow, good luck and let us know how it goes
