If you are looking to purchase/upgrade your Spark, here is what I have learned so far:
Storage bin: A must!
Speed ties: Hugely useful and easily worth the money, especially in a marina environment.
Fenders: see speed ties
IBR: I don't have it and frankly, I am glad I don't. Sparks stop so quickly that a brake seems redundant especially considering the cost. It also appears to make basic maintenance more of a challenge as it is one more part that needs to be removed (People with IBR could speak with greater knowledge on this though)
Manual reverse: I ordered it and am waiting on it to be installed by dealer. Again, I am not sure it's necessary as I have been fine without it but I can see where it would make life a little easier when trying to dock.
Tie downs for the back of the Spark/trailer: Incredibly, my dealer didn't even mention tie-downs, but trust me...get them!
Seadoo emergency kit: Necessary but you can get the exact same thing from Walmart or Canadian tire here in Canada for a fraction of the price. I assume the same would hold true for the fire extinguisher.
Registration: Go to your local DMV and ask some questions. It is not expensive to register the Spark and Trailer on your own.
I will leave all the mods/tunes to the experts but I hope this is some help to fellow noobs.
