Much discussed topic here.
There is no good option list for all people.
One thing to keep in mind though,.....the best Cayman for you will be the one with the least amount of options that suits your needs and likes. In other words, don't add options thinking you will get more out of the car at resale time. And while many owners tell themselves they will never sell this car, the truth is most will sometime in the future.
Having said that, $20k of options may only translate into $2k over a Cayman with no options in the resale arena. So choose wisely and make your brain work a bit, not just your heart!
I love my Atlas Grey paint, and chose it because it was "only" $700 at the time, then two years later it became a "special" paint (yeah right

) with a $3k price tag. Would I have still chosen it at $3k,....heck no, and it may only be worth $100 to the person I sell it to in the future. So get what you like, but be sensible.
